Today I was sick from school and decided to take a nap to make myself feel better. I thought it would be a good time to listen to an mp3 because I was in the mood to fully relax and let go. So I got into my bed and closed my eyes and began listening to the mp3. I started feeling tingles and about 3 times throughout the 35 minutes of the mp3, I had what seemed like a full body spasm where every muscle in my body seemed to twitch. After each spasm a wave of numbness went through my whole body. A car alarm went on outside and I was woken up, but I am wondering if I had SP or if this was just part of the stage of relaxing? I know that there are little muscle spasms as you relax but my whole body shook instead of one particular area having spasms.
