I have had two very strange experiences in my sleep, the first at 22yrs old & the second at 35yrs old; after explaining them to someone I was told it was AP. The first was the strangest, I was being summoned by someone who used to look after me as a youngster, and at the time she was dying, however, she did pull through (died a few years later), I wasn't particularly close to her and could not understand it at all - but both of them seriously freaked me out.
I felt myself 'rise above' my sleeping body and was being beckoned towards this woman - I knew it was her, but she appeared to have no features on her face. The second, again I was 'rising above' but it was as if I was being 'carried' - there were 2 people in this, though I did not recognise them as anyone familiar, again they had no features on their faces.
I awoke immediately after, on both occasions - and was frightened and very confused. I'm not a particularly vivid dreamer as such.
I'd be interested to know if this was AP - or just a very vivid, weird dream...!
