The ex in In dreams

So I had a weird dream about my ex last night. I don’t know how this came about but he was at my house and at one point he implied that he wanted to uh go down on me. So he ended up doing that and he wasn’t very good lol or at least not like he used to be. I kept trying to hide him in my basement (thats where we were) and from my dad and eventually my sister saw him but she wasn’t pissed like I thought she would be. My sister also had weird blond curly hair in the dream that she had dyed (she’s a brunetter in real life) and some girl was walking behind her. Strange as hell. Don’t recall what happened at the end of the dream with my ex.
