Oh, I got another good one, although again less like an SCP and more like one of those " I have to do a job and there are a strange set of rules" horror stories, I had this same dream 2 or 3 times, and I kinda want to have it again so I can keep trying to figure out what's actually going on.
I was out on a country road at night, there was a nearby 2 story house with all the nights on but nobody lived in it.
Maybe it was a foreboding feeling of being watched of being watched when I was outside in a dark completely open area, but it felt like I was being drawn to the house for one reason or another.
I went inside and felt the illusion of safety from whatever could have been outside, but I'm sure the house was actually no safer than being outside.
In both dreams after stepping in the house the doors would close and lock themselves, the lights turn off and on the television a demonic skull appears and appears to tell me something, I couldn't understand exactly what it said but I knew what it was trying to tell me, if I'm agreeing to say here I have to follow the rules:
Rule Number 1: The doors will unlock during the day, but I cannot attempt leave for any reason until a certain number of days have passed.
Rule Number 2: If a black cat approaches the door, let it in and take care of it until it leaves.
Rule Number 3: If something else approaches or knocks on the doors or windows at night, ignore it.
Rule Number 4: If the television turns on again, be present in the living room and listen closely to further instructions.
There may have been a few other rules I don't remember from the dream, but I never saw anything past the second night, having no choice but to stay in a house haunted by a demonic entity and follow it's rules, or keep wondering on foot in the country in the middle of the night and risk being caught by whatever else is out there. What would you pick?
