Since I was a kid I was fascinated by the idea of astral projection, but our neighborhood was too noisy for me to get into the right state of mind to do it. Then once when I was in my 20s (I think) I nodded off on an unusually quiet day and felt myself drifting upward from my body. I thought "This is finally it! Now, just like I always read, I'll turn around and see my body attached to me with a silver cord." Then the imp in me took over and said "On the other hand, if this is all B.S., I won't see anything on that bed." Of course, the bed was empty.
True believers would probably say it was a dark omen. Whatever.
