I'm coming down from a very strange experience. For the last ten or fifteen minutes I've been sitting at the computer, my eyes captured by the monitor's glow. I was paging through my friends page while having the distinct sensation of being something on the order of 30° from vertical with respect to the floor, which seemed to slope up to the right. The computer desk, meanwhile, sloped down to the right. "Swimming" is a word used to describe, I believe, the way my head felt. I was able to read and comprehend some posts, but on others the sentences didn't synch up. I've been aware of a sensation like hunger in like my belly. A "pet me!" visit from my cat brought me down a little, but not very far or for very long.
The horizontal surfaces have stabilized and now I'm just in a bit of "deep focus" mode; I still feel somewhat distant from reality. The only thing I've consumed since communal breakfast was a travel mug of gunpowder green tea over the course of several hours.
When people express surprise at the fact that I don't smoke marijuana, I tell them that I'm calm, spaced out, in tune with the universe, and hungry most of the time anyway, so there'd be no point getting high. Apparently I can have mild hallucinations induced by iTunes, Safari, and Mail.app too.
