Alice in Wonderland syndrome (AWS) causes temporary episodes of distorted perception and disorientation. You may feel larger or smaller than you actually are. You may also find that the room you’re in — or the surrounding furniture — seems to shift and feel further away or closer than it really is.These episodes aren’t the result of a problem with your eyes or a hallucination. They’re caused by changes in how your brain perceives the environment you’re in and how your body looks.This syndrome can affect multiple senses-vision, touch, and hearing. Time may seem to pass faster or slower.
