WARNING: You will not believe this dream. And I will not blame you for it. I wouldn't believe anyone who claimed to have this dream, either. This will also be long, tedious, and test your attention span. Thank you.
In the beginning, I was at my friend's house (even though I only know this person via the internet, and not very well for that matter). For some reason I wanted to take a shower (which was conveniently in the bedroom. Not in a bathroom in the bedroom, just the bedroom itself) so I decided to look for some towels. In one of the closets in the room, for some reason, was a bunch of my underwear, neatly folded, along with some towels. So I took some of the towels, along with a fresh pair of my clothes into the shower, even though they would get wet. I didn't want people seeing me getting dressed (despite the fact that the shower was made of that glass that you can kind of see through, though not very well). Then my friend's mother came in, opened the shower door, and told me "Let the cat in at 1:30." I tried to remember this, but forgot eventually. When I looked at the clock, which was conveniently in the shower (I was still in the shower at this point) it was around 1:50pm, so I jump out of the shower (I'm somehow magically dressed now) and go to the door to see a cat sitting before me, wanting to be let out. But I couldn't remember if I was supposed to let the cat out, or let him in and someone had already done that, or what. Then I think my friend's mother came back suddenly and let the cat out. I really cannot remember.
Then I remember sitting on the couch with my friend, who in reality is sixteen, but in the dream was a nine year old Jewish boy with glasses, and that fanciful beanie. So we're watching TV, and talking, and cuddling somewhat, when all of the sudden my mother enters the dream (she looked like Heather from Silent Hill 3, though. This entire dream is very Silent Hill-influenced). She was wearing fishnet stockings that only reached up to the knee. Suddenly, the stocking on her left leg grew a mouth, and that mouth grew extremely large, and began spewing blood. The mouth then rampaged around, killing everyone and everything, except for me. Then I remember looking at what appeared to be a map, and in the lower right hand corner of the map, there was this small box. The box was filled with certain symbols that represented the presence of monsters, and two of my dead friends (apparently this wasn't the first time my mother had killed a friend of mine). So that made me very upset. Then the dream changed, and my mother, sister, and I were all in our kitchen, and my mother was standing in the corner of the kitchen. Here's where the dream begins to sound extremely made up, and rather cliché. Her eyes turned this super bright light blue color, and blood began flowing out of her mouth. She was looking upwards, and saying something, but I don't remember what she was saying.
So at this point, I'm fairly certain my mother is possessed. She did not seem to see the seriousness of the situation, however, and just blew me off when I tried to talk to her about it. Then once again, the dream changed. I was in a different room and I was on my bed, but the room wasn't my room. It was either made of wood, or just extremely rusty. I don't think there was a floor, either (in fact I'm fairly certain my bed was simply levitating). So I decide to call my best friend, to discuss the recent events of my mother becoming possessed and killing people and such. So I call him, and we talk, and I'm all like "You're not going to believe this, but I think my mother is possessed." And he wasn't taking it seriously, and eventually had to go. So I was alone again. Once again, the room changed, and now I was in this room entirely made of what appeared to be flesh. As if I was inside of something. One of the walls was entirely taken up by this huge metal mouth-esque type of thing, with rows of metal teeth. The mouth opened and closed in a rhythmic fashion. It also breathed fire! So at this point, I think to myself "Wait... Maybe this is a dream. IT HAS TO BE." So I begin to change my dream as I'm having it (which is hard to do, but I was able to do it. Unless I just dreamed that I was dreaming and that I changed my dream, which would be weird), and I thought "What are the happiest things ever..." hoping that maybe happiness would triumph against evil, horrible thingies. My first thought was "Disney Princesses" (why? Heck if I know), so there they were, and they all started flying and fighting the evil in the room (what they actually had to fight, I can't remember. Whether or not there were monsters of some kind in the room, along with the mechanical mouth, I can't recall. Perhaps they weren't actually fighting anything, but in my mind they were helping me "fight" the bad dream). But, alas, they failed, which was oh-so disappointing. Basically at that point in the dream, I committed suicide, but that took me into the room below the one I was just in (the walls and floor were the same). More spikes, and I forget what else. But I think I just committed suicide again. Then I was outside. It was foggy and I remember a chain link fence. I think they (I have no idea who "they" are) were giving me a final chance to escape, so I start running, and I'm suddenly this robotic acorn with legs (reminiscent to the Pokemon "Seedot"). Another, bigger, fatter robotic acorn with legs then begins chasing me. It suddenly turned into a racing game, and there were these pads on the ground that would make you go faster/spin if you ran on them. This race was in laps, I'm not sure why. But right as I was about to win, I finally woke up.
This dream will forever top all dreams I've ever had, or ever will have.
