A scary story

The last weekend when I was going to the market I walked around in a deserted museum. When I am next to the museum, I heard a person who is screamed. When I went inside the museum, I see that a monster was trapped at the top of the museum. next to the monster, I see a stone, people. Quickly I run into my home and I told, my parents. They came with me to see but when they came the monster isn’t heard but the trap was opening and, on the carpet, there are pieces of stone. My parents said to me that I had slept when I was in the museum but I believe that I see the monster. I could feel another set of eyes watching me.
