Dream About Ex Showing Up Unannounced

My ex showed up at my house unannounced and crying like crazy. Me and my mom was confused and stressed about how she got there, she was with a person that said she was drunk and strung out and that my house was the only house she knew of. I said okay, I'll let her stay in the living room for a few hours, then I'll find somewhere to go. The friend handed me my ex's dads urn, my ex immediately was like no! I told her I got it. She then continued to cry and talk about how she told me already that it took her a very long time to get her daddy's ashes, she really cares about the ashes and doesn't want anyone near them. I continued to say that it's fine, I'll take care of the ashes. She says okay, sits back down on the couch and continues crying. I go to my room to process what's going on and why she came to my house. I get a call from my friend and decide to have a conversation with her for a while. My ex starts to yell that thats why me and her never worked out, I was always on the phone with my friend. She starts getting disrespectful with it, by calling her out of her name. My friend overhears her and gets mad and starts going off. I told my ex to calm down and chill. My friend gets irritated and hangs up the phone. I get mad too once I noticed that she hung up and that my ex was the problem. My ex continues to throw a fit in the living room
