Recently I have been getting this feeling I can only describe as the common pins and needles feeling and a shocking electrical feeling. I've gotten those feelings occasionally, usually when i'm not meditating.(I actually can't recall having that feeling while meditating.) The first two times I've gotten those feelings where quite painful and the last few times, it wasn't as painful like before. I've established the fact that it was bio-electricity but from where? Was it my own? or Some other being's?
