Macropsia

Macropsia is a neurological condition affecting human visual perception, in which objects appear larger than normal, and the subject smaller. It is the reverse of micropsia.

Causes of macropsia include migraines and (rarely) complex partial epilepsy. Temporary macropsia can be also caused by the actions of various psychoactive drugs, notably cannabis and [[magic mushrooms], in particular the Amanita Muscaria mushroom, as referenced in Alice in Wonderland. Drug-induced changes in perception subside as the chemical leaves the body.
