Astral Projecting And A Spirit Keeping Me Stuck

For the past 8 years I've been astral projecting myself onto a higher plane field so to speak since I honestly don't really understand much at all. All I know is for the past 8 years I've been trying to leave my body subconsciously, but there's this demon/spirit I honestly don't know what or who he is but he keeps me stuck, barely out of my body but enough so I can't move or speak or anything.

At first I called them my waking dreams since I didn't understand what they were. He wasn't in any of them until the past two times I've tried to project myself in my sleep. The first time I actually got to see him, he was only a dark figure holding a table saw, he used it on me. He tried to kill me with it. Or maybe he was testing how close he could get to me. I don't know, but the last time I saw him which was less than a week ago he was able to touch me, not my body but my spirit, I could feel his hands like I could feel yours, he grabbed one of my hands and my leg and started to pull me into the couch where I was sleeping that night, I tried to scream I tried to move but to no avail, then out of nowhere I heard someone tapping on my window, tap tap tap like as if someone wanted me to wake up, then as soon as it started I was back in my body, and I looked out the window but no one was there. I believe that someone doesn't want him to drag me under where ever that place is, it's become so bad I can't sleep, or I don't cause I'm afraid the next time I see him he's going to kill me basically, drag my soul down to where I don't know where, and keep me there. I was wondering if anyone knew of ways I could control my astral projecting or maybe prevent me from doing so or maybe ways to get rid of this man who doesn't want me to project myself like I've always done, ever since I was little. I really need help, it's to the point where I'm afraid for my life, my soul. Please help me.
