I often get that feeling, like the old saying chills running up and down my spine. Usually it is the spine where I get this, really weird feeling. The pulsations I get all over but that is more like a feeling that the muscle is jumping.
A fm friend of mine gets the same thing but we both really get the chills also.
I am finally back here. I had web tv and the service was getting so bad, had a hard time getting on a board. I have a lap top now so you will be seeing more of me.
