Lilliputian Hallucinations

also known as Todd's syndrome, Alice-in-Wonderland syndrome or AIWS, named after the novel written by Lewis Carroll;

-is a disorienting neurological condition that affects human perception.

-can be caused by abnormal amounts of electrical activity causing abnormal blood flow in the parts of the brain that process visual perception and texture.

-patients with certain neurological diseases have experienced similar visual hallucinations. These hallucinations are called "Lilliputian" which means that objects appear either smaller or larger than they actually are.

-Patients may either experience micropsia or macropsia. Micropsia is an abnormal condition of sight where the person sees objects smaller than they are when hallucinating. Macropsia is a condition where the individual sees everything larger than it actually is.

-The eyes themselves are normal, but the sufferer 'sees' objects with the wrong size or shape or finds that perspective is incorrect. This can mean that people, cars, buildings, etc., look smaller or larger than they should be, or that distances look incorrect; for example a corridor may appear to be very long, or the ground may appear too close.

-The sufferer may also lose a sense of time, a problem similar to the lack of spatial perspective. That is, time seems to pass very slowly, akin to an LSD experience. The lack of time, and space, perspective leads to a distorted sense of velocity. For example, one could be inching along ever so slowly in reality, yet it would seem as if one were sprinting uncontrollably along a moving walkway, leading to severe, overwhelming disorientation. This can then cause the sufferer to feel as if movement, even within his or her own home, is futile.
