In hinduism and buddhism these are called Kriyas. They are nothing to fear. It just means that you are getting more spiritual. In the ashram where I used to live they gave courses called Intensives where many people experienced such physical processes. They are known to Christianity but are more likely to be manifested as bleeding, like of the palms, or speaking in tongues.

You might also contact www.the-atlantic-paranormal-society.com where the sensing of dead spirits is understood.

So you are getting some gifts from God. Just try not to take advantage of them or the whole process will backfire on you. Try to feel the love that usually accompanies the process. Do not use the gift to read people's minds. And be very careful to avoid negative thinking. Just love everybody and everything will turn out OK.
