A guide to all 40 achievements in Hypnagogia 無限の夢 Boundless Dreams! I organized it by world, with screenshots to help!

Before You Continue…

I played this game blind, and I feel it would be a disservice to you all to not suggest you do the same. It’s a beautiful and lovingly-crafted experience and since there is a level hub unlocked after completion, it is not a chore to replay levels for achievements you may have missed.

This is also an (obvious) SPOILER WARNING for almost everything in the game. I would imagine most people are aware of that, given the nature of the guide, but… still.

Thank You To:

Jeff Enjoyer

You helped me with the few achievements I was missing! I will mention each of them again in the section in which they helped me. Appreciate y’all a lot 🙂

Bird’s The Word

Bird’s The Word

Gather Hypno’s details on the situation

Yes, this one has it’s own section. Why, you ask? Apparently, for some users it has not been unlocking properly and, as far as I know, is one of the few missable achievements that can only be done in the story mode.

Unfortunately, I forgot the exact steps I took to unlock it, but I do remember that when Hypno asked if I had any questions, I asked them all.

If you don’t want to risk missing this achievement, I recommend taking a look at this guide. – [steamcommunity.com]

Story Related Achievements

All the achievements in this section will be unlocked if you complete the game once, regardless of what you do or do not find throughout your experience. There should not be a way to miss any of these.

Snake Eyes

Obtain the second dream shard.

Modest Mushrooms

Obtain the third dream shard.

Warm Reunion

What A Long, Strange Trip It’s Been

Complete Hypnagogia: Boundless Dreams

Dream Hub Plus

Unlock the Level Select Mode

To unlock this one, you may need to go to the level hub from the main menu after the credits have finished rolling

Cave World

Under New Management

Complete the secret Hell World dream.

Finding the entrance to the secret world in Cave World is fairly straightforward. Progress the level up until you convince Sage Bernard to return to Foreman Fran. Then, instead of taking the minecart back up, jump into the pool of lava located behind him.

Complete this secret level, and you should be rewarded with the achievement!

Mist World

Misty Gallery

Find the secret fanart gallery in Mist World.

To unlock the first of the four fanart galleries, you will first need to complete the level up until you are imbued with the knowledge of the snakes’ language. Then, make your way to each of the four corners of the map. Each corner will have a monument to a snake of a different color. In the corner behind each of them, there is a floating object.

(example)

For each of these you collect, the text will say something to the effect of “part of a path has been revealed”. Once you collect all four, make your way up to where you talk to Water God Althos. Turn around, and you will see a set of platforms.

Jump across these and walk into the book to access the first gallery and unlock the achievement.

Fish Food

Complete the secret Underwater World dream.

Once you acquire both the red and green vials and bring them to Althos, he will present you with the second dream shard. However, instead of grabbing it, take a look down at the whirlpool again.

Huh. I can’t put my finger on it, but something seems… different. There’s only one way to investigate something like this. Take a big ole leap of faith and you’ll be transported into the Underwater World. Complete it to unlock the achievement.

(Personal note: I found this secret world on my first playthrough and it marked the point that I absolutely fell in love with this game. Huge props to sodaraptor for creating something so beautiful.)

Mushroom World

NOTE: This one is going to require a reset

All of these achievements take place after you acquire the machete and cut down the bamboo trees blocking your path.

Frightful Freckle

Get the jump on Gardener Freckle.

HUGE THANK YOU TO Jeff Enjoyer FOR THEIR HELP WITH THIS ONE!!

On your way to the temple, you should reach a bonfire where you would turn right towards the temple. Instead, turn left and take the path until it reaches an overlook of the village.

From here, jump down and land near Gardener Freckle. You will know if you did it because she will react without any further input.

Vine Shrine

Find the hidden Vineshroom tribute.

Once you reach the temple, instead of interacting with the door, jump on top of it and go to the back right corner. If you look down you should see a small cluster of trees (they are in the direct center of the following screenshot)

If you walk into them, it will take you through a short tunnel and out to a single hut. You should receive the achievement upon entering, but if not, interact with Vineshroom.

Tsundoore

Charm the Weird Door in Mushroom World.

If this achievement is unlocked, Door-zoned cannot be unlocked in the same run, and vice versa. You will need to reset the level for this, sorry.

All this requires is a specific set of dialogue. Choose the following responses:

(for the last response, you can read the other ones without ruining this one, you just have to wake them up again)

Door-zoned

Get denied by the Weird Door in Mushroom World.

For this one, you’ll just want to relentlessly flirt with Weird Door until you become too weird for them.

Pun-shroom

Listen to all of Advisor Mung’s bad jokes.

HUGE THANK YOU TO [TSOM] MannOfTheHour FOR THEIR HELP WITH THIS ONE!!

After either opening the door or getting door-zoned (in which case you are down astronomically bad), return to where the bonfire was. Here, you’ll find Advisor Mung. He’s who will give you the solution to Weird Door’s riddle, but he will also be there if you managed to woo them. Regardless, you will want to keep talking to him and hearing his Funny Jokes until the achievement unlocks.

Snow World

For this world, do everything in the snow area before you complete the secret world, because if not, you will need to reset the level.

All You Need Is Love

Find and hug all 6 shivering settlers in Ice World.

This one is probably the hardest one to explain without video, but I will do my best. The first two are relatively easy to find. Jump down until you reach the traffic light, and look to your right. There should be a ledge to jump up onto nestled against the wall (in the screenshot, it is in between the two streetlamps on the right).

Jump up onto it and follow it until you reach the first Settler. Once you warm them up, look across the street. You should see another fenced roof, and that is where the second Settler will be.

Continue on. Before you reach the frozen-over lake, enter the hollowed-out building to your right. Settler #3 will be there.

After you hug them, go around the corner. Before you reach the two children having a snowball fight, enter the hollowed-out building on the left. There’s Settler #4.

Past this building, but before the final one, look to your left again. There should be a small portion of a building jutting out of both the ground and the wall. Jump on the car, then the truck, then onto the roof. Settler #5 is there.

Do not jump off this roof yet. The 6th Settler is on the second floor of the final building where the quest to find the lost dog is acquired. From the corner of the roof you’re standing on, jump onto the fence. Then, walk to the ledge of the building and make your way into the second floor. The final Settler is waiting in the back corner.

Friendly Encounter

Pet the dog in Ice World.

If you didn’t get this on your first playthrough, I am giving you the most disappointed look imaginable right now.

Winter Memories

Help the hidden Snow Child rea*semble Mr. Snowman.

After rescuing Biscuit, leave the cave but do not jump down. You should see a small ledge to your left.

Follow this until you reach a cave. The child will want your a*sistance in building a snowman, so you need to find a head for him and a carrot for his nose. These are both located in this small cave. The head is on the right side and the carrot is on the left.

Desert Gallery

Find the secret fanart gallery in Desert World.

There are three achievements located in the Desert World, including the one for completion. To reach the desert world, make your way to the cave where you rescued the dog, and jump down onto the first building, then cross to the other, using the streetlamp as a bridge.

Continue along the ledge and you should see a wall that looks pretty fake.

Walk through it and stare deeper into the small monument located within to enter the Desert World.

To find the Desert Gallery, a key is needed. To locate this key, exit the cave you started in and make your way to the opposite corner of the map (You’ll know you are at the right point if there is a purple monument there). From there, you should see a row of stone arches.

Walk through them and immediately inside the building should be the chest. Retrieve the key.

From here, walk out past the couch with the Napping Wanderer on it. If you look across the path, you will see a building. Walk alongside the path until you reach the arches.

Cross the path, jump onto the ledges on the left side of the building and use the key on the door to access the gallery.

One Last Ride

Ride the Strider before leaving Desert World.

After the monuments are activated and the Desert World begins its shift from Hot to… Not, talk to Trainer Val and ride the strider and recieve this achievement.

Shifting Sands

Complete the secret Desert World dream.

Finish the Desert World dream.

Space World

Callous Penchant

Press the Shapezoid’s mysterious red button

As you make your way through this dream, you will come across a T-shaped intersection, the way forward being blocked by a locked door.

Go left first and speak with the Shapezoid. He makes some pretty interesting inferences and tells you to come back later. Return to the intersection and continue with the level until you have to come back through the previously-locked door. Speak with the Shapezoid again. Press The Button. Do It. Press It. It’s A Big Red Button C’mon Dude You Know You Want To.

Haunted World

School’s Out

Complete the secret School World dream.

There is two different entrances to this secret dream, both of which are before entering the mansion.

The first entrance is in the graveyard. If you go to the back left of the graveyard, there should be an open grave. Jump down it.

The other entrance is on the path leading to the mansion, so you’ll want to get the key from Groundsman Grady. You can’t really miss the well, but here’s a screenshot if you were staring at the right wall the entire way up to the mansion.

School Gallery

Find the secret fanart gallery in School World.

The picture for this one’s a pretty good hint. If you interact with the vending machine when you first see it, not much will happen. Continue until you get the absolutely terrible flashlight from the Utility Room. Go back to the vending machine and interact with it. If that doesn’t work, either try interacting again or walk back up and into the room with the broken light, then back to the vending machine. Once you have the key from the vending machine, return to the double doors leading back where you came from.

Turn left past here and you will find the Principal’s office, and inside the 3rd fanart gallery.

Mansion Gallery

Find the secret fanart gallery in Haunted World.

Continue the level as normal until you get into the library. Talk to the ghost and then wait until you hear a distinct sound of something dropping. Go to where the ghost disappeared and it’s our lucky day! They pooped out a key before ascending to The Great Void!

With this key in hand, return to the main room of the castle and use it on the locked door which I mistakenly opened before screenshotting, sorry 🙁

Grimthorn’s Shadow

Read all 5 chapters of The Rapture of Grimthorn.

Page 1 is on the table in the room with the INSANELY LOUD clock

Page 2 is in the room with the ghost banging their head on the desk (you have to talk to them twice)

Page 3 is in the opposite room, on the end table

Page 4 is in the library, from the door go all the way back and to the left, it’s on a desk.

Page 5 is on the left side of the elevator, in the corner.

Greedy Sweets

Complete the secret Candy World dream.

After you meet some new friends and take the elevator back up, you’ll return Ghost King’s freakishly large heart to it’s bony vessel. Once you do so, you’ll notice the painting above him change.

Use Ghost King as a stepping stool to reach it (it’s okay, he’s just a skeleton with a big heart so he can’t feel physical pain).

Yeow!

Find the hidden meat.

So, for this one, we need to get into the bas*ment of the castle again (y’know, where the elevator was). Head down the path and approach the castle.

It’s pretty heavily fortified, so we’ll need to look for another way in. Head to either the right or left and make your way around to the back to the secret entrance.

We just need to approach this pile of trash and interact with it to reveal the tunnel in. Do so.

Oh. Welp. Nevermind.

Mall World

You Weren’t Careful

Clip out of reality

This one’s pretty much at the start. After “Gogi” runs away, go to the diamond in the center of the room. Turn right and walk down the hall and through the wall.

Games Galore

Find the secret arcade in Mall World.

Once you manage to clip back into reality, head to Merrils. Near the exit behind one of the big pillars is a lever.

Flip it and head back towards the big ole globe.

The arcade should now be open.

Mall Gallery

Find the secret fanart gallery in Mall World.

Head back to Merrils and up to the second floor. Turn left at the top of the escalators and move towards the counter. You’ll see a tastefully distressed hand-stained 1 of 2 t-shirt, and beside that should be another lever.

Pull that bad boy and head back out towards the globe. The last store on your right is the gallery.

Tower World

Spraytagged

Find the secret fanart graffiti in Tower World.

HUGE THANK YOU TO Gator FOR THEIR HELP WITH THIS ONE!!!

This secret is on the second tower you climb, near the top. Here is where you’ll want to drop down.

The easiest way to know is to look down and, if it doesn’t look like the top layer of lasagna, it’s probably it. Another metric I use is if you jump past this and see the platforms for the next tower around the corner (like the following screenshot), you were at the correct spot.

Dream Hub

Showcase

Find the secret game model gallery.

This is last in the guide because ideally, it should be the last achievement you do. There is spoilers for pretty much everything in the showcase so I would only access it if you both have every other achievement and are satisifed with the amount of exploring you’ve done.

Go up to the cave world platform.

Behind it is a set of barely visible platforms that you have to jump across. Falling will give you a slightly better look at them.

Those are not lighting artifacts across the middle of the screen. Those are the platforms.

Conclusion

This is the first time I have ever attempted writing a guide like this, and although it took a good bit of my day, it was really fun to do. I got to play some more Hypnagogia and enjoy a lot of the beautiful levels again, which was a major plus, and I’m filled with the hope that this will be of some use to someone.

Naturally, since this is my first time writing something like this, I do not expect it to be without flaw. If there’s something you see that is either lacking in information or is just plain wrong, please don’t hesitate to let me know!

I’d like to give a thank you to everyone that worked on this game, there wasn’t a single part of it that I felt was lacking. Honestly, I stumbled across this game randomly while browsing tags on the steam store and bought it on a sort of whim, and I don’t think I’ve ever been happier with an impulse buy.

Thanks for reading and have a great day!

Here we come to an end for the A guide to all 40 achievements – Hypnagogia: Boundless Dreams guide. I hope this guide has helped you with your gameplay.
