On Thursday, I had a very peculiar thing happen to me. I had slept from 12:00 AM-2:00 AM, then woken up to do homework, then gone back to sleep at 5:30 AM. As I was going to sleep, it hit me that I felt extremely "high." My head felt completely different than it ought to, as if I'd consumed a massive amount of caffeine. The minute I moved my head, the high disappeared.

When I did finally get to sleep, I had a lucid dream. When I woke up, the high was still with me. It gradually faded over the course of the morning and was not unpleasant, but it was a bizarre experience. A year ago, I remember having a similar feeling nearly every day for a few months. I went to a doctor, who gave me a blood test and checked my blood pressure but was unable to find the culprit.

I'm wondering if any of you have had similar experiences...
