Thanks for all the info, I actually just came back from a nap where I think I made some headway. I felt my body fall asleep around my mind, what a weird feeling!

If you'll pardon my stubbornness though, could you explain the "sitting up" part? Because that's actually what ended my nap, I thought I was relaxed enough (my whole body was tingling as if I had a headrush all over) so I tried to sit up in my bed, but I ended up moving my physical body and I lost the feeling. I just don't understand how it should feel--do I try and instigate the feeling, or do I sort of wait for my body to be ready?
