Pittsburgh and hot shower?

Date: 1/12/2017

On my way to Ohayocon. I have a long layover in Pittsburgh (which looks like Providence) and meet up with a guy I sort of know. We go to an indie bookstore. I go to his apartment to nap/shower and keep thinking I've lost my phone or jacket. When I go to shower, the dial goes from "hot" to "324 degrees". Someone has written in sharpie on the tile, "if you like 324 you're a bad person!" Later as the dream gets more lucid I realize I still have my phone and everything.
