I hate astral projections,it comes to me naturally, i feel very disturbed at night! any ways to avoid it? thks

at first i had slp paralysis, then i felt as if my "spirit" is floating away? i had this thought of other spirits might tak over my body if i leave so i tried all means to move, like focusing on moving my fingers, it helps. But i fall aslp after a min and the cycle comes back again! pls advice me on how to avoid it, i had many slpless nights, sometimes i even fear of falling aslp, it happens 4 times a week on me.. pls help =(
