Weird things happen when I meditate...

Sounds like you are feeling Chi energy moving to and from your body. It's very real. there is a cool hand test on you tube somewhere and what you do is close your eyes and face the palms of your hands together but dont touch them.

Move them gently away from each other and back towards each other again, say from 0.5" to 3". Keep doing this and concentrate, moving your hands slowly in and out.

when you do it right it feels very strange like magnets between your hands puching them apart or something.
