Lost in the MET Again

Just in case you take my warnings about getting lost in the MET lightly, on a recent visit, I found myself trapped between what appeared to be a crawl space. I turned down a stairway and found myself surrounded by two brick interior walls, like you find in a crawl space in old buildings. Oh, well, they had art on these brick walls and I eventually found my way back in the main hall. The question is, could I ever find those brick walls or stairs again? Or was I actually in a forbidden space filled with dark secrets of stolen art and haunted artists. Sounds like a good plot for a movie.
