I have weird sleeping tendencies, are these normal? or happen a lot?

Ok all of this is going to sound weird, but I need to know if I am sub consciously trying to kill myself lol!!! When I sleep sometimes (about every week to two weeks) I smother myself when I sleep. My mind quickly picks up on that so I am aware that I can't breathe so obviously my brain tells my body to move, but it doesn't. I just can't seem to move at all, and I panic and I freak out and I feel like I am screaming but I am not and then right when I feel like I am going to die my body wakes up and moves!!!! Another weird thing is sometimes I will lay down and relax and I am very comfortable like I am beeing hypnotized (which btw is the ultimate relaxation lol) so I am awake and aware and then my body just goes numb and I can open my eyes but I can't move my body or speak. It is very freaky, like when I wake up I am so scared, I am paranoid I am being possesed lmao, which I knwo isn't true but still scary non-the less. So I was just wondering if this is normal? If this happens to a lot of people? I asked my doctor and she said she had no clue what I was talking about and had never heard of this happening!!
