Seeing the World (and Writing It) with Alice in Wonderland Syndrome

Many have speculated that Lewis Carroll took some kind of mind-altering drug and based the Alice books on his hallucinatory experiences. The truth is that he too suffered from the condition, but in a more severe and protracted way, and had many episodes of AiWS and ocular migraine. My experience of aura, and the distortions of memory it can cause, led me to write about another character who believed himself to be reincarnated, as a way of making sense of memories that did not seem to be from his own life—again, an experience extensively explored by Philip K. Dick.
