How do I know if the sensations are electrical?

I thought of the Kundalini, but maybe it's the warning signs! I feel alot of vibrations inside my body when I meditate or listen to the paraliminals. Maybe it's a beginning of Astral Projection or maybe it's an Energy! Who knows!

However, I've improved in my mental abilities alot more than before and can think clearly. So, Am I in danger or something?

Thanks to everybody for helping me!
