Last night's dream

Last night, one of my dreams involved wandering through a large, palatial building that was part library, part museum, part bazaar, part performance space. Architecturally, it was a strange mixture of Boston Public Library, Olin Library, the Isabella Stewart Gardner Musuem, and a whole bunch of other such places I've been. I walked past a wall of abstract paintings, through a room filled with booksellers, a small room in which a musical performance was being given, through library stacks, etc. Oddly enough, this place has appeared in my dreams once before. Last time I was there, I was only on the outside of it - it looks like the kind of building you'd expect to see in a film production of a Jane Austen novel. I think I may have been either trying to sneak in or break in, but I'm not sure why or to what purpose. And it was summertime, whereas in last night's dream I know it was winter because I was alternately wearing and carrying a heavy coat. I'm sure there's some interesting symbolism and meaning here, but I don't know exactly what it is. And to tell the truth, I'm not terribly concerned about it, either, because both dreams were so enjoyable that I'm sure this isn't about anxieties, or problems, or anything like that.
