I had a very intense and detailed dream last night where I was in a huge, very old, hotel. I was thinking it to be 6 stories but was large in breadth. It had very dark wood, huge hallways with high ceilings. I think the building was either a large rectangle or a square with an open courtyard in the center. It was something you would think of at Halloween.
This dream occurred after a thunderstorm passed through and I fell back asleep.
