I was in one for about 3 days when I was in college when I first became diabetic. It’s kind of strange, I can’t remember ANYTHING about the time when I was in the coma, but when I came out of it I definitely knew that a lot of time had elapsed, and it wasn’t like I was asleep for a night or something. It felt different. But there were no dreams or anything like that. When I came out of it, basically I was healthy as a horse, there were no after effects from it, but it did mess up my mind for a while. I had a sort of amnesia for a while, where I could REMEMBER everything, but it didn’t feel like I had experienced any of the memories. It was like being able to go and read all the books in a library, but not having read them before. The memories were like brand new when I remembered them. Very strange. And I was like that until one night when I realized that a Jimi Hendrix song had some sort of meaning to me, and I mechanically went into my bedroom, got the album out (we’re talking late 80’s here), put it on the record player, and balled my brains out while I listened to “Are You Experienced?”. That’s what broke the tide and started bringing me back to myself. It still took another couple of days, but the docs said it was all normal.
