Dream About Brother Missing Locked Himself

Me and my parents were on a trip on a coast . We rented an Airbnb for us and then one separate one for my brother, who got the , to live by himself while we stayed there. We went to visit him every night to check up on him but he looked rather weird. He wouldn't talk to us much and when he did it was about how much he hated being alone. When we wwre heading out to our own Airbnb he locked himself in the bathroom and I gave him a heads up and said "finally" we were walking home when we encountered a fmaily fighting some kind of villain because they were kicked out of their hotel. We decided to ignore it for the most part and we went to a kiosk. The weather was dark and cloudy, but still pretty warm. In the kiosk I met a girl who looked like we had known each other for ages, but when I wanted to get my candy, all the candy I wanted was prohibited because it was allergenic. When I was heading back home I saw a plake with my brother's name on it, saying he had gone missing, but it didn't actually have his name, it was a random name that I for some reason associated with my brother. We got home and I called a few friends to help me find him, and we started looking for clues and all we found were my prescription meds, which seemed a little weird.
