Dream of doors, killer, euro, woman, child

I was in an empty room with three stranger, two boys and one girl, one of the boy had blue hair and a cool look while the girl had twintailed curly hair and an innocent expression; we had to escape together from the mansion. we walked toward a door and found ourself on a path with beautiful trees on the sides. we used a motorcicle that was parked near us to try and escape but suddenly one of the guys remembered that he lost some money in the previous room. The blue haired boy decide to go back and search for the money of the other guy despite the dangerous situation. I decided to go back as well and tried to drive the motorcicle without success. when we got back, the girl noticed a door that we hadn't seen before so she went toward the door with the boy who lost the money to explore, leaving the searching to the blue haired boy and me. We found two pair of ten euro on the floor and I took them to give them back to the boy who lost them. I went to the other room. On the floor, covered in her blood was the twintailed girl, dead, while the boy that lost the twenty euro stood there, a knife in his hand. he looked at me, a twisted grin on his face. he grabbed my t-shirt and pushed me on the floor than he walked in the previous room and locked the door. I tried to open it without any success; the blue haired boy was in danger with that Killer. Suddenly I heard a mechanic rumor and a little girl's voice:"Where are you?" she singed. Sensing danger, I walked toward every door I found but each of them was closed. finally I found myself at the end of the corridor, there were two doors, one in front of me and one on my right:"I'm coming" the girl said. Scared I pulled the door in front of me open and found myself in a room filled with strange looking people. one woman who was seated on a trone looked at me and decided that if i could win three trials, i could continue my escape even without companion. I found myself duelling with a plastic weapon against a girl and I won. in the second trial I found myself challenging in a music contest a small child with familiar features. the child played a familiar avventurous song, he was really good at it, I had little to no chance to win. In that instant the blue haired guy and the Killer entered the room. "You!" I screamed running toward them to punch the killer. the woman on the trone made me stop with a commanding look.
