Nap WILD Attempt

I went for a nap WILD this afternoon. Normally, when I take a nap, I have one hand over the other like a dead man at a viewing. This afternoon, it must have been about five minutes until something strange happened. In my left hand, was a virtually indescribable feeling. Almost as if it was getting repeatedly blasted with "paralysis" or some kind of "paralyzing feeling." I tested the movement in my hand and it was able to move well, and the feeling would dissipate after I did so. Nothing else of significance occurred.

What happened here? Was I close?

I also tried to do a nap WILD today. I did not get past the full body numbness, and it was at the point where it feels like you whole body is being pricked by pins, like after you move a limb that was asleep. I did not achieve lucidity because I was laying backward on my bed and, due to a lack of a pillow, I had to consciously swallow drool, as it did not drain down through my throat naturally. However, I kept trying for at least an hour, and my whole body felt impossibly heavy. So much in fact that I did over 5 reality checks just to make sure it hadn't worked. was this close or was I being prevented from making much progress by the pillow situation?
