Wrong place

*I got hit in the head yesterday by my friend's fist (it was by accident) so that might have something to do with this dream.* ***Please let me know if this was lucid or not! Thank you!*** I was staying with my grandparents in what seemed like this mix between a mansion, an apartment, and my house. I think it was haunted. I was looking at a painted family portrait and I remember being intrigued by a little blonde boy. I pointed him out to my grandmother, but she said he was no one. I somehow knew that it was her son who had been lost/died and (in the dream) I think I knew that I knew that because I had had this dream before. I was walking in an abandoned hospital with my best friend <PERSON>. It was all dark and musty. It may have been storming outside. This ghost of a nurse ran by me. She was dressed in the stereotypical nurse's uniform; mid-length skirt, button-down short-sleeved shirt, hair in a tight bun, and cap with a red cross on it. She said hi to me as she ran by, and I said hi back. I was in the basement of my house. There was a a heavy-set woman with thick curls and glasses sitting in my dad's arm chair. I asked her about my grandmother's son, but the woman said he never existed. I was exploring my grandparent's house. I came across this one room and opened the door. The room was pitch black. I turned on the light, thinking I was going to find like a dead body in the bed or something. Turned out to be my grandfather in the bed who I had awoken when I turned the light on. The TV was also on. I was in this school like building with <PERSON>. We came to this padded area. Two of the gym teachers from my middle school were there. They told us we had to stay there. Something bad was happening, but it was never specified what exactly. There were a bunch of other students sitting on the mats. I knew we needed to escape. I asked <PERSON> to go get my shoes that we had left at the other entrance. While she was gone, I knew from my previous dream that there was a way out. I found a door that led into a gym. She came back with mine and hers, too. I was putting on my shoes, they were flip flops, and they ended up being the ones I have in real life, black with a paint splatter pattern. Then we both bolted through the gym. I was walking up the stairs to the back door of my house, which leads into the family room. My mom was there, and so was this girl I go to school with, <PERSON>, and her mom. <PERSON> admitted to having something to do with the ghosts. Then I woke up 10 minutes before my alarm went off :-(
