This dream was the first murder dream I have ever had.
I remember that I was in this really big house and for some reason I saw one of my teachers in a night gown. I told her that there was a girl in the other room. I watched as she left and waited at the door for her to come back. She never came back and instead I heard a blood curdling scream. I then saw on a computer screen (it was a night vision camera) that she was murdered by this girl I saw earlier. I ran off and ran into a back room to which I found a tv. On the tv, I saw myself as a kid playing video games on a tv (I never remember this happening) and then I stopped and ran into my room to get a basket full of airplanes (I loved airplanes as a kid and had over 300 airplanes in a collection). I watched until I noticed a rather attractive guy standing behind me. As we started to talk, I noticed that he was Russian and had a thick accent. I started to get to know him and was genuinely happy as I realized that I had fallen in love with him. We spun around on chairs and had a lot of fun. We walked out of the room and ran into the girl, so we quickly ran off. When I looked back, the guy was gone. Holding back tears, I ran out and hid behind a tall cabinet and looked across the room to find another girl hiding. We stared at each other in terror. I looked to find that I was not completely hidden and the girl (the murderer) was standing right in front of me. The other girl was obviously murdered before I could scream. I got on my knees and begged for mercy. She pulled out a knife and began to tell me how she killed the other 3 people (the guy included). She told me that she shoved a knife up the other girls crotch and let her suffer and bleed to death. I was mortified. I took the knife and stabbed her without thinking and ran for the door as I found that she was not dying. The last I remember was walking out onto the lawn (which turned into my friends house and I was in her yard now) and falling onto the grass. I remember that some cars pulled up to help and some were even carrying bags. I told them what happened and they looked concerned. I also told them why I had murdered the girl and that that's why I was all bloody.
I did not watch anything scary before having this dream.
