I'm just curious if anyone else has anything like this.
I have had several dreams over the years that I'm discovering a secret room. I even remember one from when I was a kid (I guess that's not so strange, I remember dreams I had when I was 4 but I have trouble remembering things that happened to me in the waking world when I was a kid). The path to the room is always the same, and I always recognize it. I always think "I'm about to visit the room again!"

There's nothing special about it, aside from the fact that it's a hidden room. Here's the path I always take: I'll be walking past a doorway in an abandoned or vacant house, I may have walked past it before in the dream but this time it looks familiar. I become aware that I'm dreaming and I'm about to find The Room again. The interior of this room is a little messy, piles of clothes or junk everywhere. On the far side of the room is a painting, behind which is a small tunnel or crawlspace that leads to another room that is also full of junk. I know that I'm the first one to enter the room in many years. This room is connected to another by a short and narrow hallway, in the next room there is a heavy, wooden double door. I go through it and there is a staircase (usually a spiral) that goes down. I never make it all the way down the stairs, but I'm always trying. I want to see what's in the room at the bottom of them.
