Apparently, I had a step sister I did not know about living with her mother and her "evil" step dad -I put evil in quotations because he never really did anything evil in the dream but that was the title I was given in my head- . She was around 8 years old and wore a blue and white dress with white shoes. She had straight then curled at the bottom brown hair with a bow on top. The whole scene was sort of old fashioned or like something out of an old movie. I could never see her mother's face but I did get a glimpse of her step father sitting on one of the single couches ( elaborately decorated with a shiny wooden frame). The sofa/chair was a light shade of blue with little embroideries in a shiny paler blue. The step father was wearing a blue suit (darker than the sofa/chair) and brown shiny shoes. He was basically in formal wear. He also had a dark tan and a salt-pepper mustache. His hair was combed in a comb over and he held a ciggerate in one hand and an old newspaper in the other. You could tell the newspaper was old due to the yellowing color. I only got his profile ( long straight nose and thin lips) because the back of the chair was facing me. He didn't say anything but turned back to his news paper. Then a man ( who was supposedly my father but was a shadow to me and spoke and acted differently from my father) greeted my step sister and then told me that we had three days before traveling back. And that I would get one day with my step sister to "hang out". I smiled when she turned to me and expressed my excitement at having a new sister. She smiled back shyly then we were all "transported" to a different area.
I then had sort of a "flash back" where I was looking at a mountain of dirt with heads littering it like large rocks on a mountain. I then saw my step sister's head in the middle and she was bleeding from her mouth. I worried that she was just a head but then this woman burst into the door ( it was all sort of in slow motion from there). She had long white hair but she was young. She looked distressed as she ran over to my step sister and pulled her out from the dark mountain of dirt. Turns out she wasn't just a head but buried in there. I then found out that I also had a step brother. Also, very young in age but with short brown hair and again old clothing but for little boys - sort of resembled sailor clothing - white and blue (white stripes).
Then I was "transported" to the supposed kitchen/cafeteria area in an old brick building and watched where a kid unknowingly walked in to have all the large wooden doors shut suddenly and the heavy windows to lock. Outside you could see a snow storm starting to begin. Then the lights inside started to flicker and a monster ( no other word for it except maybe alein in a semi humanoid form with long legs and arms, a very darm green almost black, and with a face that is indescribable but the sharp blood stained teeth in the middle) comes running from somewhere to sink its teeth into the boy's flesh then proceed to devour him entirely. I watched three of those kinds of murders happen. I also watched as my step brother almost enter the room but then got distracted and walked in another direction. Then I watched as my step sister ( suddenly a teenager now with long brown hair) almost go in. I don't remember why she didn't. She spent a long time in the snow watching the entrance while all I could see was her back.
Again, I was "transported" to another room while I had to stand behind a large piller while two sides fired ammunition at each other. I could see the bright flames from supposed gunshots but heard nothing. Then someone came into the room and pulled me and my step sister who was now a little girl again out of the room into a room with red and gold carpeting. There was a wooden booth nearby selling some objects - don't know what exactly. And that's it, I don't remember the rest. If I do I'll add it on here. But yeah, this dream definetly ranked as one my top ten freaky nightmares.
