These things happened to me when I was in my late teens, and I found them both disturbing and fascinating. The one big moment was travelling on my Honda 90 on a main A road in the Midlands, when I found myself looking down on other drivers and myself, riding my machine. I had to halt and pull to the side, just to stop shaking.
Other times was when in bed, and I could travel to nearby places, before I found myself once again in bed. These were disturbing and soon stopped after I met my future wife and began to settle down, and I have never suffered since. incidentally, I never took drugs and am life long tee total.
