Terrifying strange nightmares

So I wake up pretty much every morning in a cold sweat because when I dream I have these terrifying dreams that are incredibly realistic, ex. Last night Iad a dream where my baby cousin learned to walk but she then wandered out a door and got ran over as I went to her corpse I just blinked and ended up in a pretty much dark room except for some blueish lighting from some weird lights, a weird animal with a mishapen head begs at my feet and rips my pants legs to shreds, looks up and says this in a really creepy as fuck voice "You cry at night don't you? Wake up before you forget how to. Or else~" it doesn't matter about the first part of the dream but after I see something sad or tragic happen to me my family or friends I'm always brought to the room, every time it's slightly different though, once the animal was in a tank as a huge goldfish thing, the other time it greeted me ominously like a gameshow host, and a few more times in a sing song way telling me that there was a date due for something that was late soon, that's a legit quote from it, I remember all these dreams exact pinpoint detail and wake up with the feeling something is grabbing at my hair and my right ankle and wrist, the only thing that leaves a mark is on my wrist which is just some really weird scratch things but I don't sleep with jewelry or anything like that. What the fuck is this?? (Comment please?? Looking for what this is??) I've heard of recurring dreams but they are different each time but always focus on the same layout and end with that weird animal, and why are there scratches on my wrist? Another slightly unimportant thing is that I hear this scratching sound like someone rubbing paper together and then this weird hiss almost, like a hedgehog or turtle? Hear it every time I wake up but nothing there at the bed of my feet. Also I don't normally remember my dreams in this amount of detail and it all feels so real, sometimes I'll just wake up in the room without me blinking and the animal just stares at me or makes sounds, even more scary it's not in short bursts it feels like HOURS, a legit play by play and I'm really scared to sleep now because I hear the same noise after I sleep and the animal itself is really weird, it changes sometimes but you can always tell it's the same thing as before because of the voice. The scratches aren't deep but they are very thin and nothing I sleep with is sharp, in the dreams I am wearing shorts and a tank top that says lazy days but it changes from that to my underwear and socks with a fitness shirt with the shoulders cut out. The dreams before the animal are always kinda fuzzy but identifiable, like you are shining your phone screen at something in a dim room. The animal says really creepy things like "Never watch yourself sleep because you will not want to meet yourself when you wake up" or "you know me in the shadows near the chair" which was really creepy since I didn't know what it meant until my sister pointed out that she put my bungee chair under my bed which is the only chair in my room. Another example "look as hard as you want you won't forget me" , "the pricks on your heel, yea that's me" it likes to talk in third person too "you left your window open" , "you are wearing too tight of a shirt to feel the sweat beading down your back" this one terrified me cause it rang in my head all day "you were afraid of the dark as a kid yes? (I responded yes although it doesn't do conversations like this normally) well I was always there when you suddenly felt ill and you had the pressure on your head of a thousand industrial bricks, the moment you thought something moved in your room or you saw something in the corner of your eye, I was there (I didn't know what to say so I asked for an example) you'd think it would be just yourself if I only said things about you so let me tell you this, your sister felt a grip on her ear when she slept for 6 weeks straight in 9th grade (how do I know you aren't lying?) ask her yourself" she said yes and said she never told a soul. That night I woke up my sister and asked her, but I sleep on my side with a body pilllow, my hands and legs were completely numb. Someone please for the love of god tell me what this is before I ask it myself because this sure as hell is not some figment of my mind telling me in exact detail a secret of my sisters that she never told anyone.
