Katsuno's Awesome Ninja Tales!

1st: I was inside a gym with my class. We had to do some tasks like playing soccer or sprinting to get score (it was like in a game). Suddenly there was a sewer entrance instead of the door. I walked through and somebody said that there are baby crocodiles in the sewer and we need to kill them before they grow dangerous. We walked along some planks and beneath us was deep water. It kinda reminded me of Batman Arkham Asylum where you have to fight Croc. Suddenly something moved underneath us. Everybody got scared and ran into a different location. In the next moment a gigantic crocodile jumped out of the water and got one of the guys. I got really scared and hid inside a small tube. I looked to the other side and there was a baby crocodile. When I tried to shoot it (I randomly had a pistol) it grew huge and tried to bite me. I jumped back and ran away. The next thing I remember is that there were many mutant crocodiles killing all the people and as one of them got me I woke up.

2nd: I was inside a city that looked really old (maybe like from those cowboy movies). I was inside a room and with me was a girl. Suddenly somebody screamed and I looked outside the window. I witnessed how a women got impaled by an invisible creature. We locked the door and that girl asked me what's going on. I answered "I have no idea but be careful!" Suddenly the door opened and I heard some footsteps coming near. Somebody punched me and it really hurt. I noticed that the invisible creature was actually a man. I punched in the air but I didn't hit anyone. Suddenly I could feel his presence. I grabbed his leg and threw him against the wall (I was super-strong ^^). The girl was like "How did you know that he was there?" and I told her that I could see them now. Another one walked in and I punched him in the face. He got knocked out and the dream scene faded. The next thing I remember is that I was sitting in front of my Computer and surfing the internet.
I woke up
