Sounds like your speaking in tongues or something. It probably is related to Kundalini, but I'm not too sure. You don't have to be "skilled" enough for it to rise. Another sign of a kundalini awakening is a warming sensation around the back, mainly the lower back rising up through the Chakras. Did this happen? Kundalini can just happen. Be careful with it though. It's a beautiful thing, but it's also quite the devil if you let it get to you. If I were you, I would chill out with mediating while stoned for a while. Maybe just do some yoga poses and mediate sober. I never experienced anything like what you have, but it's different for everyone. I know I've reached very high states while stoned and even sober. I find it best to do it naturally, just because it's safer and you don't go too high too fast.

But by all means don't take my advice. I'm no expert.
