Alice in Wonderland syndrome (AIWS), also known as Lilliputian hallucinations is a rare neurological disorder. It causes changes in visual perception, body image, and experience of time.

​

It is a rare condition that 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.

​

This syndrome can affect multiple senses, including vision, touch, and hearing. You may also lose a sense of time. Time may seem to pass faster or slower than you think.

​

AWS primarily affects children and young adults. Most people grow out the disordered perceptions as they age, but it’s still possible to experience this in adulthood.

AWS is also known as Todd’s syndrome. That’s because it was first identified in the 1950s by Dr. John Todd, a British psychiatrist. He noted that the symptoms and recorded anecdotes of this syndrome closely resembled episodes that the character Alice Liddell experienced in Lewis Carroll’s novel “Alice’s Adventures in Wonderland.”
