I 'attempted' a WILD after a short WBTB break as I had nothing to lose, as I usually drop off to sleep to carry out (if I'm lucky) a DILD early morning anyhow. I use the acronymn 'DILD', but generally I just become 'aware' it's a dream usually.

I just wanted to see what it felt like. I did reach the SP stage with the odd hypnagogic image afterwards - however after an hour I must have fallen asleep.

The SP feelings, which included the tingling, the numbness, etc. I encountered were absolutely amazing. It was worth it just for that alone, in itself!
I would'nt go as far as to say it was orgasmic, but it was a great experience. (This is from someone that has already had SP in dreams.)
Although I didn't 'WILD' as such, as I said I was attempting LD with my usual WBTB method.
However my main question is this: I have had these sort of feelings in waking life (usually when relaxed) even with eyes open, where your body feels all warm and numb, even to the point you do not want to move to break the relaxation.
I think even one time I felt this, it was as though I felt smaller.

So are these feelings of relaxation, or what? Has anybody else experienced this when awake, for example in the middle of the day?
