I know I'm asleep but can't wake up

I have regular nightmares where I know I'm asleep but can't wake up, the things in the nightmares are unbelievably disturbing and when I eventually wake, my heart is racing and I'm confused and can't think properly. I sometimes see things and if I fall asleep again the nightmares continue so normally I have to call someone or get up and do something until the confused fear ends.

Anyway, the most recent one was last night, again I knew I was asleep and I was begging for help but everyone around me was morphing and saying creepy things or they just couldn't hear me. The dream kept sort of restarting and each time I'd 'wake up' in bed and try to figure out if I was really awake this time or not and every time I came close to waking up, it would restart again.

The final time it restarted, I tried to use my phone to contact someone and when I did, I got a text from an anonymous number saying "Stop trying to wake up Ellie" and when I asked why I got another text saying "You are my berserker" and then the word berserker was sent on repeat getting louder and louder and louder till I woke up.

I am not someone who normally believes in spirits and things, but this was such a weird feeling that is completely supernatural. Has anyone else had dreams like this? Or been called someones berserker? Just interested to see if this is more common than I thought. I can't find anything that describes what these nightmares are because it's not sleep paralysis and it's not just a normal nightmare. Please let me know what you think. Thank you xoxo

I'm dealing with something extremely simar to you. I've never been called a "berserker", or felt like I was being haunted in my dreams though.

I have reoccurring nightmares where I know I'm dreaming but I can't wake up.
I keep fighting and fighting to wake up just to realize that what I've woken up to is just another dream. I'm clawing at my arms, I'm slapping my face, I'm screaming at myself "this isn't real", "you need to wake up", "Wake up!", "WAKE UP!!!"
It's terrifying. Feeling like I'm trapped in my own head.. Feeling like I'm going to BE trapped in my own head.

The context of the dreams are always different, but one constant among them is that I see and interact with my immediate family (which just further jacks up my concept of reality).
I usually find myself in very random situations and settings, usually with this getting weirder and creepier as I realize I'm dreaming and try to escape. Disturbing creatures and monsters make an appearance here and there as well, but the biggest fear I experience is knowing that I'm dreaming and can't wake up and that fear keeps on building and building the longer my dream goes on. The fear that I'm trapped there, and that no matter what I do, or how hard I try, I'm not going to wake up.
I can't even say for sure how many time I've "woken up" in my dreams before I actually wake up wake up for real.
Each time I'm left with a cold sweat, a racing heart, and a nothing but thoughts of the dreams I just had.. emotionally exhausted and scared to go back to sleep.

Today no monsters are creatures showed up, just a lot of common place settings with commonplace interactions.
Today I ended up falling asleep on the couch with the the light on above me; so those lights are what I saw at the start of each new dream cycle where I was "waking up". I was desperately fighting to open my eyes, fighting to move my body, heck even trying to squirm my way off the couch.. anything in a desperate attemp to wake up.
(I think of this portion of my dream as like the bridge dream between dreams, where I'm experiencing something like sleep paralysis and can't move despite fighting to wake up. ((knowing that I need to open my eyes or physically sit up or stand up in order to stay awake)), before finding myself in the next portion of my dream where I think I'm actually awake.)
So like, a family member would be there and say "yeah, you were sleeping for a really long time" or "yeah you were doing some really weird stuff in your sleep", which would reasure me that I was actually awake, which I was not.
New situation.
New dream.
New fight.
Over. and over. and over again. Never ending. Never waking up.
Constantly fighting, until I indeed actually woke up.
Scratching my arms and slapping my face to reassure myself that was actually awake. Brain fog and and nothing but memories of the dreams I just had running through my head.
