Sick Dreams

I'm sick, so that may explain why this dream is so weird. First I was at a house with a bunch of other people, and we were all playing instruments. Not instruments like guitars or keyboards, but instruments like a marching band would play. There was one dark haired guy in a white t-shirt who was playing a flute I believe. I think I was playing a clarinet, and we kept dancing around the room and playfully bumping into each other, so I figured maybe he liked me. Later he disappeared and I was kind of sad. We stopped playing and I offeres for rhe remaining pelple to come watch anime with me and was happy to see that flute guy had came back. I was then walking with a guy who called himself Shaggy. He was a black guy with dreads. We were walking through some kind of graveyard or obstacle course (I can't remember, just know there were obstacles). We were talking about the origin of his name and he told me his real name was Shaggy. We went into a store of some kind and as we were standing at the counter, people in the store kept making weird comments like "it must be great when The Joker takes care of you" and "wait until Harley finds out." I was wearing a gray Harley Quinn t-shirt, and I faced the man beside me who was now a white guy with mild Joker make up. I giggled and said "too bad they don't know I am." "Harley?" he asked me, and I nodded and proceeded to rock back and forth on my feet like a child, grinning playfully. We later left to drive by the obstacle course thingy and called some friends of ours who had previously said they wanted to explore it and told them we were driving by if they were interested. They told us they had just walked through it and we were a bit annoyed that we had missed them.
I don't really know if this is in perfect chronological order as it was a long dream. I feel like the Harley part was the end, but whatever. That's my weird dream.
