Dream About Concert And Argument

I had a dream where I was at a concert with my girlfriend and her friends, and I wasn’t Vibing with her friends that much so I ended up leaving my girlfriend to go with one of my friends to a different spot at the concert to get a better view of the artist and have a good time. After the concert I remember she got a little upset at me and I getting annoyed at her. This is strange because in real life, we don’t get into arguments like that. I had another dream that my girlfriend and we’re staying at a tiny house that we rented. She did something before we went to bed that frustrated me and I woke up before her as she was still sleeping. I noticed that she also responded to one of my friends on my phone in a rude way without even telling me and decided that I was just going to leave but before that happened I heard someone coming into the house. She woke up and there was this younger Hispanic guy who seemed to be intoxicated or out of it. When I opened our bedroom door and confronted him he seemed all dazed and confused. Being flustered and not really knowing what to do He picked up a knife from the kitchen and tried to come after us. I picked up a pillow to protect us and attempt to take him down but the dream ended.
