The house and the curius

One day while I was walking in my neighborhood I saw a strange house I decided to go in the house .when I was walking to open the door, the door opened alone, I was scared but I wanted to know what inside the house. While I was looking inside I saw stairs in the left and it was broken. While I was tried to open the light. I saw a black cat came from the stairs I screamed then I ran out the house.
