I have talked to and read about people who say they have experienced the Kundalini rising. One of the main differences that I have found is that Kundalini is a kind of force/spirit which won't leave easily. That would make it a from of possession. God is a gentleman. He will only come where he is invited and will leave when no longer wanted. You must seek Him and His presence. He will not take over you and corrupt your free will. Kundalini and other spirits will.
