To 'darkness house'

I went to "darkness house" with my friends on Monday. It's near London Bridge and it was really cool! When I first time came in I saw a woman which in a long black coat and smile to me but I saw her mouth were full of blood. Then I just run away with my friend. This time I saw a lot of skulls around us. After few minutes walk we are in a perplex room which was really dark and all made by mirror. We used nearly five minutes to find the way out. Then we saw a lot of sculpture about how people dead in the early 18 century. It was horrible! People kill others just like kill a fish or a chicken. They think kill people as easy as play a game. After I come out, It’s still terrible to think of. I think I won’t forget it.
