I had what you might call a brainshock last fall. I was trying to get to sleep one night and then I started realizing a tingly sensation in my head, almost like electricity was passing from the left halve to the right halve of the brain.
Then I was out...except it was far from unconsciousness. I will mention that I could see nothing and wanted to see nothing. I felt that I was unconscious and yet there was consistently a period of what I felt to be electricity going through my head at regular intervals for about 20 minutes, each burst occurring every approximately 10 to 15 seconds.
I couldn't get my balance or my bearings. I thought I was going to die. Then I really blacked out. When I woke up, I felt like I had been hit by a truck.
hehe. Sweetness.
Jam it back in, in the dark.
