Dream About Climbing A Snowy Mountain

This dream was about

I was in school when someone told us that we had to go upstairs to catch the bus. We went up about 1000 stairs, and when we got there I found a few friends. However, we had to keep going up, amd when we did, I found around seven guys talking about who will get down what. One of the youngest guy said he will go down with the harness and he got a rock, which was what they were trying to get down a very snowy mountain that was breathtaking. When he was going down he fell and lost the rock, so he had to get his phone and call one of his friends. He called and then they told him that that wasn't their problem and to just go up already, but he said that he wouldn't go anywhere wothout the rock and just kept going until he reached his goal. Afterwards he came back, full of scraches, but he finished what he started. Then my dream zooms out and turns out it was just a video, and not real, so I told my friend who just appeared next to me that it was just a video. Then I heard my parents talking in a very worried tone about something I'm not so sure about. They are talking about a game created by the mafia where a tall monster with long arms and long legs starts following you until it catches you and tickles you to death. Just when they were done explaining I see the monster walking past my neighbours house and scream. I tell my big brother and we hide behind the couch, but when I think we are safe, my brother turns into the monster and starts running around trying to tickle me to death, so I fight him, and he turns into another person, so I hit him harder because he is not my brother and then he touches me sp I'm supposed to turn into the monster but I didn't, so I fight him even harder and we end up leaving the house so that the mosnter isolates himself.
