The brain apparently produces its own antipsychotic drug. Says The New Scientist:

At some point in their lives, between 5 and 30 per cent of healthy people have had symptoms such as delusions or hallucinations, which can be triggered by something as simple as sleep deprivation. "All of us are potentially psychotic," says David Castle of the University of Melbourne. So for the body to have a system that prevents these experiences getting out of hand makes sense, he says.

Obviously this is grounds for a special impromptu "Use Your Delusions" Backwards City event. I'll start. I was telling this one to some people over the weekend:

In the year 2000, while I was living in that tiny house Boston with every person that I knew, I fell asleep one night in the living room while we were watching some bad direct-to-video murder mystery movie. At that time, it was just me, Sal, Sheryl, and Lindsey in the house, and we were all in the living room watching TV when I feel asleep.

When I woke up, the movie and all the lights in the house were off, and everyone was gone. I don't know how long I'd been asleep, or what woke me up. But I do know that when I woke up I was absolutely convinced that Lindsey (the one person in the house that I hardly knew) had murdered everyone else--and that I was next.

In other circumstances, I would have just stayed on the floor of the living room, keeping alert for any sign of Lindsey. But unfortunately for me, I had to pee.

So I made my way through the dark hallway to the bathroom an inch at a time, convinced that any second I'd either discover Sheryl and Sal's dead bodies or be stabbed to death by Lindsey in the dark.

I was awake for at least two minutes before my delusion suddenly subsided and my beliefs about Lindsey returned to normal.

It's the only time in my life I can remember ever being completely out of my mind. It must have been some kind of weird dream hangover, or something. It was very strange. I can still recall, vividly, how anxious I was inching to the bathroom, as well as how unshakingly convinced I was that Sal and Sheryl must be dead and that Lindsey must have killed them.

Don't leave me hanging. Use your delusions in the comments.
