Hypnosis, brainwashing, mind control, stuff like that, hypnotic gas
All around you are images of yourself staring back at you. You are laying on the ground on black and white checkered tiles, surroundes by mirrors. The air has a faint sweet, candy-like smell, although it is barely noticable. You just woke up, but don't quite remember falling asleep.
But there really isn't any time to be thinking about that. You need to find a way out of this place and figure out how you got here. You get up and make your way through the maze, but you can't seem to make sense of your surroundings. Every time you turn, you're faced with countless images of yourself stretching back into infinity.
After a while of walking, nearly running into mirrors, and trying to map out the area, you start to get worried. You should have found the exit by now. This mirror maze must be much longer than you originally thought, a labyrinth stretching out indefinitely. You could have passed the same area dozens of times and had little to no way of knowing. Surely, you must be closer to the exit.
You persevere on, starting to get more and more dizzy and disoriented. You don't feel like you're making much progress, just making yourself more and more confused. Most mirror mazes arent quite so disorienting, and one usually figures it out sooner or later. You take a deep breath, filling your lungs with that faint sweet, candy-scented air. Maybe after a short break, you could collect your thoughts and find a way out. You sit down, close your eyes, and breath in deeply.
Before long, you forget what you were even doing. Your mind has gotten so fuzzy and so dizzy that you no longer can find a reason to continue on. Before long, you won't be able to move anyways. Whatever is in the air is making you so happy, calm, and docile that you forget everything else.
You hear a speaker come on, echoing softly throughout the maze.
"You've done very well, puppet. You're going to make a fine addition to my collection."
