This is one of the mental disorders that rarely occurs but is a terrifying experience. It describes a disorder that comes with a set of symptoms that alters an individual’s body image. An individual suffering from this condition perceives external objects of a different size incorrectly. The most common incorrect perceptions are experienced at night. People can see objects and things much smaller than they are and feel their bodies alter in normal size, thus distorting an individual’s general perception. The condition makes individuals hear sounds louder or quieter than the actual sounds, and some lose the accurate sense of texture and velocity. An individual with Alice in Wonderland Syndrome can be a pervert of their body image, describing it as an LSD trip with no euphoria. As a rare mental disorder, it affects individuals in their 20s with a brain tumor or a history of substance abuse.
