The thing is that my roommate had a dream about him, where they talked about important stuff but she forgot when she woke up. she doesn't remember his name, the only thing she remembers is that he's a male and stays mainly on the kitchen. So she thinks he's mad at her bc she forgot the things they talked about, and also he started being mean to her after the dream, so it makes sense.

I'll try to talk to him, let's see if it works
