Need help with Out of body experiance?

Okay, so i’ve started to try it, i’ve read quite Alto on it but last night experienced something which i have never experienced before.
I was lying down, staring at the light on my computer, for 10-15 minuets when i nodded off, i knew i had nodded off and i knew i was having tons of different dreams, but i remember each time my body was experiencing like pins and needles all over my body, which i eventually panicked each time and woke my self up.
After falling asleep again, i was asleep, dreaming of something, can’t remember what but i woke up with sleep paralysis, i was conscious but couldn’t move. I then heard a Rumbling or a vibrating in my head and maybe my body, it was in my ear too, i could hear it and feal it, i then heard a voice in my head( which sounded like a cross between a native indian and Arnold Swarchnegger, except not so strong on the accent and a softer voice) telling me something, i think it was speaking another language or i couldn’t hear it properlly, but by the tone of his voice he sounded like he was encouraging me to do something, i don’t know what but yeah.
After i heard the voice, everything stopped but it was strange, the last few seconds of the experiance i was also trying to wake my self up(usually i panick and try move) but this time i was just breathing heavily while relaxing and waiting. When i woke up, with my eyes open conscious, the rumbeling faded and it felt like everything died down.
2-3 seconds later a tinitus effect kicked in, and had a slight ringing in my ear.
I don’t do drugs, or was drinking or smoking. It’s the first time i have ever heard in my life, a voice inside my head which was not my own.
Does anyone know if this related to having an out of body experiance? if so how do i actually get out of the body? i don’t think i was trying to lift out, i was sort of panicking a little trying to understand what’s happening.
Please no sarcy replies!
Thanks
