I was having a really strange dream this morning. Anyway when I was asleep at home in bed , in the dream I was in the car with my nan who isn’t alive and she was telling me to get off my phone but I stayed on it so she started getting mad at me and she jumped on top of me and started to hit me then she put her hands around my neck strangling me. Somehow it managed to wake me up and In real life I had my hands around my kneck strangling myself and I couldn’t breath. Honestly it happend so fast that I thought maybe I wasn’t actually awake I was just scared however I turned the light on and took a picture of my chest and there was serious red marks on my kneck. Really I don’t think I’ve ever been so scared like why did this happen how is it even possible? I’m quite scared to go to sleep now it really scared me!!! Sorry but any replies will help I just don’t now what happend!
