Real Super Powers

Hey guys,

You know when you get cold and your get the shivers. Some people say 'someone just walked over my grave'.

I can make myself get these shivers and they seem to build up towards my head. It starts off weak but then gets stronger if I concentrate. I can also kind of make this 'energy' move to any part of my body.

My question is, is this a normal thing that any person can do? Or is there something more to it?

It always seems to be most powerful at my head and so far has not effected anything outside of my body.

Thanks guys and gals...
