Postpartum nightmares

I am not sure if it's even a thing as pp nightmares but I swear I never had such intense nightmares b4 having my baby. Just wanted to see if other moms had them also. So every few days, I have this dream that there is some weird energy around me like a spirit or something.. as i realize it's existence, i try to scream and call my husband's name but my voice doesn't come out. I try to move, but it feels like my body has become too heavy to move. My baby sleeps next to me and my husband sleeps in another room. Sometimes I see my baby dragged by something, and last night felt a hand on her which really scared me. It all feels so real and i wake up so scared. It happens early mornings like around 4, 5 am. Whenever i experience this, i can't go back to sleep unless my husband comes and sleep with us. I am already scared to go to sleep tonight.
