I thought I had died

Four years ago I had entered a forum such as this only to question the whole experience, What is astral projection?, but the main reason I had searched it out was because I thought I was dying, I was leaving my body up to 3 times a week after being diagnosed with a disease which turned out to be a false diagnoses.

I never knew the words to type into Google concerning what was happening to me until I typed in leaving my body at night, then answers flowed. This was a terrifying time for me and all I wanted to learn was how to undo it only to find that most people are actually practicing how to do this..Wow right!

In the beginning my experiences were terrifying such as this one:

My very first experience I heard a sound that can be compared to a roaring motor and an alarm at the same time, the volume increased to the point I became very uncomfortable  and scared, I could feel this tremendous viberation throughout my whole body along with tingling...it went on so long that it actually started to tickle the side I was laying on... I felt a pulling as if there was a magnet above me. I was so scared I woke up ... I couldn't so much as move one muscle for about a min or two which felt forever... I was paralyzed.

I stayed awake for about 10 to 15 min's in shock of what just happened and quite confused. When I went back to sleep it started all over again only this time I didn't hear the sounds... I felt the viberations and felt my body being pulled... I didn't know what was happening but I just decided to let it happen. I was laying on my side so when I had left my body it was dangling in the position that I had been laying but feeling very heavy... I was too scared to move then suddenly I was lighter than a feather, I looked around and could see everything in my room, my body was floating upwards and I remember I didn't want to go anywhere , I was so amazed at what was happening but like a bullet I started at lightening speed , it felt like I was zooming towards space!! I was absolutely terrified at this point and thought I had died!!!

I don't want to die!!!! was all I could think when I stopped ... there was complete blackness all around me .. only what it felt like seconds later I started at the same speed again coming back down... I had that feeling in my stomach as you would when swinging too high on a swing. I couldn't stop this, I could only beg it to stop.

When I did stop I was laying horizontal on what I thought was my bed because I was back in my room only that I was about 3 to 4 feet above my bed, I had looked down and seen my body laying there... how could I be here and there at the same time??? I sensed another's presence and with fear I looked to my left only to see a silloutte of a man laying next to me... there was nothing scary about him, actually he was handsome from what I could see but the fear was so intense from the beginning of all of this I began to panic! I thought to myself he wants me! And so it was , he did or because I thought it my fear came to life...
Without going to much into this part of it I will just say that at times I was fighting him but the extreme pleasure would distract me from trying to attack him... this part still confuses me some but after having hundreds of experiences leaving my body since I can look back and know that it was a fear I had in waking life and I believe that our fears can really take away from the beautiful experiences we can really have leaving our body.
I have so many more experiences that I would love to share for the first time now that I am comfortable with it , I no longer fear it and look forward to it but unfortuantley ever since I moved into my new house I have only had 4 experiences in 4 months... now I miss it and want to do what most of you are doing, learn how to do it, lol  MMMMM???? I am wondering what happened to me that I no longer do it naturally... I look forward to your replys!!!
