memorable

i was in a room with people that i knew in real life and i tapped this one girls shoulder that i had actually seen in real life a few days to a week prior and as soon as she turned around and looked at me i immediately realized it was that girl and later on in this dream me and a bunch of other people are in a school's gym and i went through a door way and ended up in a different room then another room with installation and wood in it as if it was being built then theres just all these other doorways that lead to rooms and i just kept going and going some rooms looked like libraries and other rooms had twist and turns and just yeah it seems like there is a common theme in my dreams where i'm in a place with a bunch of rooms like a mansion or a library what is my mind trying to tell me
