I've had a couple instances where I wake up from a dream where I got injured in some way or even killed, and when I wake up, I'm in some sort of pain.
Examples (all from a couple years ago):
I was chased (by a member of a band I like, IDK why.) down this walkway over a lake. For most of the dream, I was just running away from him. I got to the end of the walkway, and was scared to jump in the lake because it reminded me of this place I went to in real life where the water could leave burns from the chemicals and heat. So I stopped there, looked back at him, and when he got to me he bit me, threw me in the water, and choked me to death. (I think he also might've slapped me but I cant really remember.) When I woke up from that, I felt like someone was still choking me, and everything was really sore. The next day I had a continuation of that dream, same place, same guy, but this time I fell from a cliff into the lake, he tried to save me, but I didn't trust him, so I broke free and ended up drowning. I woke up sore and not able to breathe again.
I also had a dream where I was walking to my car in some parking lot late at night, and some guy put me in my trunk and tied my wrists. There was more to the dream but I can't remember it. The point is when I woke up my wrists hurt like they'd actually been tied.
Another one was where I had this dream where for some reason, I needed to pull off my nails. There wasn't really much plot to it except that fact. So in the dream, I kept pulling on my fingernails, getting frustrated when they wouldn't come off. I woke up pulling on one of my nails.
I've also had several dreams where I run into something or something stupid liek that, and when I wake up, I'll have a bruise or scratch wherever I injured myself in the dream. My only thought it maybe I scratched myself... I tend to keep my nails kinda long so it is a possibility. It cant be from a pet or anything cause I don't let my dog sleep in my room. (and for most of these I didn't even have a pet)
More recently, like in the past two weeks, I've had dreams which are pretty similar to eachother: I'll adopt some animal, or itll just wind up in my house, and at some point in time, the animal becomes a human, who tries to kill/hurt/abduct/etc. me. Whenever I had these dreams, I'd wake up feeling like somethings sitting on my chest, so I can't breathe.
