Dream About Crowd Gathering Around Bike

I had two dreams. The first I was riding my old red bike and me and my two friends went to a supermarket, so I parked my bike withy chain. But when I got back from the supermarket there were a small crowd gathering around my bike. They were trying to unlock my chain. I thought my chain had fallen because it has fallen this day but I managed to realize and lock before getting in the supermarket. So I got in the crowd and asked what they were doing and they really were trying to unlock so I decided to wait and see if they could do that. I looked around and saw two women looking worried and excitedly to find money inside of the folder that was connected with the bike. I showed my tongue to the women attempting to say that they won't open it. She went straight to the chain and tried to do herself but she couldn't. After a while the man opened the chain but as expected there were nothing but some tools in it. The man was clearly upset but he did that to entertain people so he wasn't upset for real. Then my dream switched in a secoind. I was gonna have a test for my school but it was a writing test which is very uncommon in my school as my school is for actors and voice actors in real life. It was a rainy day and we went to a big city as the school reservd a room in a building for us. After doing the test we were going to go to a studio a little far from there so we let some baggage inside the room. However, I forgot something inside my bag so I returned to get it when I saw some other students using our room too. I got confused because I thought the room was just for us but it seemed it wasn't. I just went straight to my bag to take what I forgot and tried to go but I heard one of my classmate saying "to achieve things, you have to work jard no matter how hard it is. But don't forget to take some breaks." And while I was thinking about it, I saw a boy, one of my classmate but I don't recognize him in my waking life and a girl, one of my closest friend starting to act strange. As if they were possessed. So I started to pray by instinct. I noticed it was working because they looked at me right away and my friend jumped on me. She was trying to bite, and she actually did. But it didn't hurt. As if she was saving her strength to not hurt me but she couldn't stop biting me. And while she was doing that I was praying all the time, and when I finished the second version of praying I woke up. That's it.
