Wow!
Frist time ive seen someone post about this on one of the trading forums I frequent.
Yes, I get this, and it is FREAKY!! I get it approximately once every month or so.
I haven't even bothered to look at the links yet but im assuming its the same as what I get.
Basically I fall asleep, and then at some point my senses seem to wake up without me. I can hear the TV if its on for example. Sometimes I attempt to 'throw' my arms around as I sleep in an attempt to wake myself up. The first time I experienced this I thought I was about to die!!
lol
I now notice that I am more likely to get it if I sleep on my back.
I kind of experience the 'ghost feeling' you mentioned when it first happened to me, but that could also be bacuse I was so much more afraid than when it happens to me now??
Its so weird though. I tried to explain it to some of the guys at work and they all thought i was nuts!
