There are various events that can be found within Amillusion that can be triggered by doing certain things across the dream world, such as interacting with an NPC in a special way or performing a specific action. This page lists all the events that can be found, where they may be viewed, and a brief description of what occurs within them. Please feel free to expand on this list with any new information or events.
Aerobus
Location: Coco Desert, Corrupted Notebook, Danaë's Room, EPACSE, La Pigne, Rainbow Screw Floor
Description: Interacting with the circle sign will cause an approaching helicopter noise to play. Danaë will then look around and spot the Aerobus and she will make her way inside the bus. Once inside, you will need to wait a certain period of time to arrive at your destination.
Chicken Revenge
Location: Desolate Desert
Description: Entering any houses in Desolate Desert from the door on the right side has 1/52 chance (1/32 with Mad Key) to start the event. The room will suddenly become red once you enter, and with chicken clucking and static. Eating sounds can be heard at the end of the event, at which point Danaë will scream and wake up.
Doomsday
Location: Ruby's Power Plant
Description: Upon entering the world, go left, down, left, up, take the second left, and finally take the second up. You will arrive at a small platform with a mad scientist on it. Equip the Brambles key and he will take out a remote controller. If you attempt to attack or get too close to him while he has it out, he will press the button and laugh manically, launching tactical nukes and bombs down onto your head. A loud explosion will be heard and Danaë will immediately wake up, presumably having been blown up and killed by the nuclear explosion.
Elderly Woman's Rave
Location: Space
Description: Go left or right till you arrive at technicolored planet with a submarine and a water cooler with pink liquid in it. Interact with the cooler to drink some of the liquid. A grandma will then appear and flash a multitude of colors till you press the ESC button and end the event. You can also make sounds with the arrow keys while in the event. This is likely a reference to the Aztec Rave Monkey or FACE events in the original Yume Nikki.
Lockdown
Location: Residential Corridor World
Description: Enter any room with an NPC in it and equip the Brambles key and kill them. The world will suddenly go into lockdown mode and the entire screen will begin to flash red, and the music will be replaced with a loud alarm. Upon going outside, Chasers dressed in suits and a hat (assumed to staff security) will immediately hunt you down and capture you, trapping you in an empty desert (unless you use the Cosplay key.) You can stop the alarm by leaving the world and coming back.
Mad Cows
Location: Flies Platform
Description: Immediately equip the Brambles key. Once you equip it, the whole screen will turn red, the music will change, and the decaying cow NPCs will freeze and start mooing in fear. Flies will also fly across the screen at times. Attacking a cow will also make it decay into a pile of flesh and bone. The world will immediately go back to normal once you unequip the key and every NPC will be restored.
Metamorphosis
Location: Beach
Description: Find and wait for Roxane to change back into her human form and quickly equip the Brambles key and attack her. Upon doing so, she will suddenly face and metamorphose into you and starts to smile and laugh at Danaë as she starts to wither away. The event will end with a screamer and Danaë will be forced to wake up.
Organ Shop
Location: Midnight Mall
Description: Go down to the third floor and enter the double doors without any signs near it -- the Organ Shop. Here, in the Organ Shop, you can talk to the shopkeeper to sew a copy of Danaë's head on to Danaë herself for 20€ if the Shopping key is equipped (otherwise it will be 30€). This will last until you switch into a new key.
Pouleine Ride
Location: Zoo
Description: Go through the right path to the next screen then go up into a marble structure, once in the aquarium just continue upwards till you find a room. Pouleine will be waiting for you in the middle. Interact with them to start the event and enjoy the wild ride. You will then arrive at the Beach once it is over but will be unable to open your menu, you will have to force quit and return to an earlier save. (This bug is fixed on YNOProject.)
Skiing
Location: Ski Resort
Description: Obtain the Skis key and head through the barriers to witness the event. Danaë will begin skiing down the mountain at an increasing speed until she bumps into an obstacle. You will need to reach the bottom of the mountain to end this event, in which there is a ski lift that will take you back up the mountain for 2€ if the Skis key is equipped.
There is a speed glitch that can be triggered by repeatedly going down the hill at max speed or smashing into an object at max speed. After the event ends, Danaë may be able to walk at this speed indefinitely. If you try to use it, take care not to save over important files. This can be fixed by repeating the event or using the bug with the chair on Danaë's Balcony.
True Believer's Wrath
Location: Believer's Temple
Description: This place is quite huge, and the one true Believer does not have a set location as she will teleport around the map. Look for a woman that looks like the large golden statue that is also present in the location. If you find her then act quickly as if you wait too long, she will teleport to a different location. Equip the Brambles key and immediately attempt to attack her. She will disappear upon getting too close and reappear with a rabid creature. She will then place it down and snap, teleporting away. The creature will then latch onto your face and presumably start to aggressively eat you alive, red blood splatters splashing onto the screen. Danaë will then be forced to wake up.
Vaporized
Location: Space
Description: Go left or right till you reach an orange planet with a white flower border, a house, an alien girl in front of it. Equip the Brambles key. Once you do, the lady will become enraged and start spinning around like mad. If you attempt to attack her at this point, instead, she will close her eyes, scream and immediately vaporize you into ash, leading to Danaë waking up.
