The Piggy Bank

Last night I had a dream, and I remember the ending of it somewhat well. I was in a very foggy place. The air was white and I don't think I could see the sun because of the thick fog. I could see things close to myself, which was mostly the ground, which was rough natural stone. I think I had somebody with me but I don't remember who. There was a small incline to another area, and I got the feeling that I wasn't supposed to be there, or that people don't usually go there, but I climbed the small craggy slope up like 1.5 meters and went anyway. I had been standing next to a small stream with an intricate worn path in the rock ground. After climbing up, I noticed an arch, sort of like a doorway. I don't remember too much about it, but it was made of several stones and there may have been some foliage as well, and somewhere I saw letters or symbols(I don't recall if they were on the arch or inside or what). I walked around it and looked through from the other direction, and saw a small dark room(I don't remember seeing anything in front of it from the other direction, the arch stood alone I think), with some hanging moss(Spanish moss?) partially obstructing my view. I remember seeing a little bit of the color dark purple, I know that the moss was a dull grey green. Either I or somebody with me said, or I thought to myself, there is a bear inside. It wasn't scary but it was sort of discomforting. I or we kept moving, but I don't remember what else I did or saw in that rocky misty land.

The landscape was kind of like this, but with more fog everywhere. After a google image search, I know that the landscape was much like the highlands of Scotland, with more exposed rock-- but not particularly jagged rock, it was craggy but worn smooth enough to climb and walk on.

I know I don't remember much, but I can't stop thinking about that place. It was really nice.
