I had this dream a while ago, I don't remember all the details, but it's interesting. Apparently, it's a hereditary sort of dream; My mom had it, my Aunt had it, my grandma had it, and there are always some things that are the same no matter who's dreaming it. Weird. One thing I've been able to pick up, though, apparently it takes place in a place known as "Chapel Perilous"
The dream started with me on an old sailboat on the open sea. The waves were rough, and for one reason or another I had to dock on a nearby island. The shore was very rocky, and I can't even remember seeing a dock, but I kind of imagine there was one. In fact, come to think of it, what I saw of the island was basically one big rock out in the open sea, but there was sort of a cabin on top. It was a two-story wooden-plank building, like you might see in a snowy resort place out in the country. I walked up and knocked at the door and very quickly an old woman opened, greeted me, and let me in. I can't for the life of me remember a word she said, or what her voice sounded like, but I think it was just a sort of typical old-lady-voice. What's extra odd is I can kind of remember her face, but besides that, her hands, and a bun in her hair, I can't remember any other details. I sort of dully acknowledged her body, but I didn't notice it, if that makes any sense.
The inside of the building was fairly normal. It was a nice place, the door lead into a big room which probably made up most of that floor, with a tall open cieling and the second floor of that room consisting of balconies, with stairs up behind corners on the other end of the room. There were these tall things by the walls, which sort of looked like vending machines or arcade cabinets, but I don't remember any other details about them. There were these weird figures going around, operating the arcade-cabinet-things, and at that point I couldn't notice any details about them. They were sort of... shadowy, and my attention didn't stick to them. The old lady said some things and lead me down some stairs to an underground area. The next moment I remember, the wooden planks are all gone, and I'm in this somewhat dimly-lit concrete tunnel which was sort of like a sewer, descending concrete stairs. It was a very thin tunnel, and when we got to the bottom of the stairs, there was a crossroads: forward or left, either one lead to a fairly long hallway.
The old lady led me down the left hallway, and we came to an open doorway. She stepped into it and stopped, I didn't muscle past her because I was being as polite as a normal person is. The room was empty for the most part, but I could see a drain on the floor from behind the old lady's head, and then all of a sudden a humanoid figure, on all fours poised like a spider about to leap on something (even though that's not really a thing spiders do, in hindsight) and completely silhouetted-no details were visible at all-appeared from the drain. I was startled, but the old lady didn't react in the slightest, and the figure quickly sunk back down and vanished. I was left shaken, kind of wondering if it had even happened, and I just sort of followed along when the old lady continued down the hall, leaving the little room alone. We came to another door, and the same thing happened. Another room, another figure, and this time I had to ask if she saw that, or some similar question. I remember she responded, but I can't remember what she said, though it seemed offhanded and nonchalant.
At this point, I was sure something odd was going on, but I wasn't sure whether or not to follow the old lady. I continued on behind her, kind of scared, and we came to another crossroads-this one left and right. I had a chance to look to the right this time, and all I saw was like five feet of tunnel and then a wall, though I kind of remember a grate-like detail, but I've kind of been writing that off as being like a texture from an old PS1 spider man game. Before I could look down the left tunnel, the old lady pushed past me, pulling me back behind the crossroads, and vanished down the left path. I think she said something, but like everything she said, I can't remember the words to save my life. In a couple seconds, she reappeared from the right tunnel, the one I saw immediately end in a wall. My reaction was a combination of "this is terrifying and I am getting the hell away from this supernatural stuff, this can NOT be good" and "I AAAIIIIINT HAVING THAT SHIT, I KNOW WHAT'S GOING ON, I AIN'T PLAYING YO GAMES!" What I did was scream "HOLY F###!!!" and run the other direction saying, in response to the old lady's question of "What's wrong, dearie" or something predictable like that, "Get away from me!!!"
I made it to the first crossroads and turned left, away from the stairs, and ran as hard as I could. I looked behind me, and the old lady had caught up to me, but she looked different. Her face was twisted, demonic, no human should have a face like that, her hair had gotten kind of messy, and her hands were like claws. She caught my arm with one hand, I couldn't pull free to keep running, and raised the other hand to strike at me with her claws. I yelled "Wait!" and she hesitated at the top of her wind-up. "I'll do whatever it is you want me to do. I'll do what you say!" She lowered her hand and lead me back upstairs, and that's the last part of the dream which I can remember in sequence.
After that, it's all kind of a blur. I could apply my attention to the shadowy figures now, and they were these weird, inhuman, sort-of-demonic creatures, not unlike the old lady now that I think about it. But they were clearly not autonomous; they were tools of some sort. I remember some weird candy-like things that turn people into those creatures, and I remember me being in line to take them. I like to think I fast-talked my way out of that situation, but I really can't remember. I remember going around one of the corners where the stairs up to the second floor balconies were, and seeing a man chained to a shield with weapons across his front like a coat of arms on the wall. He wasn't suffering, he had a steely gaze and was looking tentatively forward. I think he noticed me, and he was definitely alive, but he didn't directly look my way that I can remember. There was something written on the shield. "Damage is true here. Be careful, Duncan." It might have been a different name, but I remember it started with a D, and for some reason I can remember it was definitely meant for me. The odd part of that is that my first name doesn't even have the letter D, and even though my last name starts with D I know it wasn't my last name. For those who don't know, true damage is a gaming concept, meaning damage which is completely unaffected by armor, defense, or other modifiers. A 23 true damage attack will always do 23 damage, regardless of damage reduction.
That's all of the dream I can definitively remember. Apparently, whenever somebody else has it there are always some similarities. There's always an old lady, there's always the weird tunnels, there's always rooms containing something very scary to the individual, the old lady is always fast and turns demonic. There's always chapel perilous, but its form changes. There are always odd figures in the foyer, as well. Supposedly the point of the place is to challenge you, determine what kind of warrior you are. That makes sense to me, I come from a family of berserkers. No, seriously. We're normal American people, but something that runs is the family is that when our fight or flight response gets triggered by a lot of anger, we sort of enter a berserk state. I've done this a couple times; it's a trip. My senses shut down except for sight, which was barely running, and I couldn't think except to feel an intense rage. No pain, no reservations, someone in a berserk state is not someone you want to get in a fight with. Maybe chapel perilous is part of being a berserker; those who are capable of going berserk go to chapel perilous to be tested in some way. Whatever it is, it was an odd dream, and I found it very interesting that most of my mom's side of the family has had that dream.
