Dear Erowid Readers: We're a small nonprofit that runs the top drug information website in the world. We have only 4 staff but serve 12 million users, and have costs like any big website: servers, power, office space, programs, and staff. To protect our independence, we don't run ads or take government funds. If everyone reading this gave $3, our fundraising would be done today. If Erowid is useful to you, take a minute to keep it online and ad-free another year!

Abstract
On a Friday afternoon, April 16th, 1943, while working in the laboratory, I was seized by a peculiar sensation of vertigo and restlessness. Objects as well as the shape of my associates in the laboratory appeared to undergo optical changes. I was unable to concentrate on my work. In a dreamlike state, I left for home, where an irresistible urge to lie down and sleep overcame me. Light was so intense as to be unpleasant. I drew the curtains and immediately fell into a peculiar state of 'drunkenness', characterized by an exaggerated imagination. With my eyes closed, fantastic pictures of extraordinary plasticity and intensive color seemed to surge towards me. After two hours, this state gradually subsided and I was able to eat dinner with a good appetite.
