Dream About Coworker Conflict

A coworker was upset with me because I didn't copy a bunch of things for them. It was 15 minutes until I had to leave for the day and that coworker was just sitting there talking with two other coworkers. I attempted to get it completed but I was running out of time so I went back and told them I would not have time to finish it. They got mad. I told them I still had to get some things wrapped up to end my day. The coworker gave me a dirty look on their way out before I was able to leave for the day and I ended up staying even later because there was a big rush of people coming to my office to drop things off. The rush left after that and I was able to get outside and closer to my truck so I could leave and then I ended up helping some other staff load some items into their vehicle before I headed to my own so I could go home. I was concerned that the coworker who wanted me to make their copies would give me a bad review to my supervisor so I thought of some reasons to tell my supervisor and supporting later events to prove that I just didn't have time to do what they needed and they had time to and could have had it done themselves if they hadn't been chatting instead of working plus they left long before I did.
