Question is this a night terror or a warning or am I just going crazy??

So to explain in more detail every other night right I get this dream/night terror which as a heads up is a dark bit scary one and might not be for the light hearted people I will warn you now. I'm in no real danger or anything like that don't worry it's just a nightmare I've been having lately apologies in advanced!

Every other night I get this dream I'm this house which is dark. I've been taken by this male and it becomes colourful let's say. Then as I'm leaving he tries to kill me. But in the dream I see and feel him putting his hands over my mouth to smother me. It's really strange as in the dream I can see and feel everything in the dream and I wake up hot, scared you know the usual emotions but feel like he was actually there. It's a really strange feeling.

I know it's only a dream. My head knows it. My body doesn't. I can't quite explain it. I don't watch/horror or anything like that. This had never happened to me in real life. Hence why me having this nightmare is bit of a puzzle. Wondered if any other dream study enthusiasts could help me out here?

I've only put this below because I know how it sounds 😊. As my friend said only I would have this type of horrible dream 🙁

*Not in any real danger in real life it is only a dream*
