I can't be quite sure if this even belongs here or not, but I think that may actually have something to do with either an apparation, or this may have something to do with an Extraterrestrial encounter, I do not know.  Perhaps someone can spawn some light on this.

Every single night, I always seem to have this cold feeling that seems to run down my spine.  All over my body, my senses seems to be alive as if something was touching them in such a way that it feels that something was throwing me around.  Some times the feeling is warm as if someone was laying next to me, and sometimes it feels like I was laying in ice and snow.

Research Kundalini, see if that fits into what you are describing. It is a very interesting subject.

This is interesting http://www.swamij.com/kundalini-awakening.htm I have learned something today

Well it could be what what was in the link, But i would wait and see, Sleep does weird thing's to the body sometimes, If your sleep wake switch does not work right. Since sleep happens in many different levels.

Very interesting none the less!

Just senses IMO. The same thing happens to me, but don't expect much
