Sleep paralyisis pretends to be my mom??

For context, this started around 3rd or 4th grade. During this (which I still remember rather vividly) I had my first lucid dream where I was the child of a couple of two rlly sweet women who were convinced they were my moms. And I kept telling them I wasnt, and that this was a dream. At some point I was outside with a girl who was supposed to be my friend, and fell off a ledge in the forest (not deadly but would hurt) and I woke up the exact way i fell. (this happens in any dream I fall.) I woke up, and felt as if i couldnt move. I realize my mom is laying on top of me, shes laying on her stomach acrossed me staring at me. This is obviously strange but I try to speak saying something along the lines of "mom I had a really bad dream." Which comes out barely and way to raspy to sound like words. She just stares at me before saying, her face completely monotone and voice the same, "I know" to which i feel my head fall back and it feels as if i cant breath, as this happens my "mom" slowly fades away. leaving a black figure on top of me and i fall back asleep.

After that I go back into the same dream, waking up horribly afraid and trying to tell my mom what happened. Now ive had similar senarios like that, and have always wondered if its because of me and my moms relationship? It happened again tonight.

Tonight i had a dream where I was in my house, nd running a bookstore out of my room (weird but dreams are dreams.) And at some point my mom shows up in my dream, and suddenly i cant see. Or its more like I cant open my eyes no matter how hard I try to pry them open. This also renders my body feeling heavy, and like I cannot move. I try to cry for help. A couple of times, I wake(?) up. Now im unsure if these times were also sleep paralyis and I was awake, or if It was just me dreaming, but Id wake up and still cant see, id try to move, try to fully wake up, but it felt as if i was trapped and id fall back asleep. This happened a few times, and then in my dream my mom was in the room with me, I cried for help and suddenly I was "awake." I see my mom standing next to me, im leaning against a stuffed animal of mine just looking at her. But then i realize "where is she standing? Im facing the wall?" where she was unless her legs where inside the bed it was impossible. And just as I realized "this isnt my mom." She looks down at me and begins moving forward, arms streched to my throat. I "scream" and then wake up, able to move and see but feeling horribly droggy.

and that leaves me to now. Im wondering if this has some sort of reason for happening? Or if anyone has any similar experiences? Because it sure is creepy. (Btw ive never used reddit before, but thought Id try so id have somewhere to share this.)
