PLEASE HELP...! My first experience with AP

PLEASE HELP...! My first experience with AP I have been trying to project since week. But every attempt I made was unsuccessful I couldn't reach the vibrational stage. Until today morning I woke up at around 5:30 I look at the window if was still dark. I thought to project but I waited until 6:30 (as I afraid of dark) lol. I just closed my eyes and drift off to sleep, now I was dreaming about myself in bed and attempting to project and was feeling some sensation back of my head. Suddenly, I realize I was dreaming I woke up but I didn’t open my eyes. OMG! I was feeling as If my head was motor and a very large propeller was attached in the very center of the back of my head and was moving. I can hear the sound it was like fluf, fluf, fluf…. I could even sense the direction of the propeller was moving (it was counter clockwise). The feeling was soothing but scary, I knew it was happening and I clearly had the feeling that I’m in a vibrational stage but I doubt it, as it was taking up speed and was moving faster and faster and I started thinking whether it was vibrations or something else was going on (at this point I was feeling as if I’m half sleep and half awake). This scared me and I couldn’t think what to do next I started saying stop stop I’m not ready please stop, and the sensation gone after a while, and I really regret to be scared of this.

I didn’t feel the tingling sensation which usually starts in vibrational stage.

Was I really in vibrational stage? What should I do when I come across this sensation? Any suggestions?? I also afraid of Dark and the feeling of separation. Please help me motivate. I just want to do it badly but I get scared. If I do it once, my fear will go away.

Sorry for my really bad English
