Do I have sleep paralysis

So right now I am 16 years old and ever since I was 15 I’ve had some weird, life like “dreams” where I was fully awake. One of my most vivid “dreams” were when I was sleeping like usual, I remember waking up, I was fully awake and aware, now I couldn’t see what was in my room because I sleep on my stomach and my eyes face the backboard of the bed frame. I heard loud heavy adult like footsteps running back and forth around my bed, I wanted to scream and move but I couldn’t. This “dream” was one of many.

I don’t want to identify myself with sleep paralysis until I see a doctor for it, but could someone explain to me what this is or could I possibly have sleep paralysis?
