Confused with my astral projection experience?

I just literally woke up and wanted to ask this question right away before i forgot everything. I had asked a question on here once before about my half awake dreams and then how they turn into vibrations and blah blah blah and how it's all linked into astral projection without me even really trying to do it. Well today is a crappy day (new england) so I've been pretty much sleeping all day. The thing is I haven't had any caffeine yet so I can usually just lay back down and fall into a semi sleep when I've been well rested and not that tired. This kind of sleep is weird because it usually starts off with me not actually falling into sleep but falling into a kind of "peacefullness". My body goes almost numb and it's hard for me to feel a pulse. When I finally convince myself it's alright I start to have half awake dreams. Being able to dream about anything, like my mind is clear because I don't actually need the rest. But in these dreams I always make weird moving motions, almost like loosening up motions such as squirming around and jerking back and forth lol sorry i have no other way to explain it, They're not painful, they actually help me feel good. After that I knew I was still half awake so I told myself "imagine I'm floating out of my body". So immediately I could see my tv in front of my bed but i was still in a "trance". All of a sudden I heard vibrating electric noises, like an electric humming. And saw electric pulses around my body and then I actually felt my body lifting off the bed. I struggled a bit and kept trying to make myself float a little. I didn't have a complete experience but it was amazing. Please any other experiences with astral projection I'm so intrigued. No rude comments. If you don't believe in it then that's fine, but I'm only looking for people who are serious on answering this.
