MY SISTER SAW GHOST!!!!!!!WHAT SHOULD I DO?

Help!Just recently my little sister whose 5 told me that a ghost that sitting on the couch, and stare at her.Next to the ghost was chuckle whom she also saw told her that he wanted to kill them all.The ghost next to chuckle was black that look like me except i am white and the ghost look black.The ghost was black, and look similar to me,and he was wearing the same jacket that i was wearing,and he had pretty much the same clothes that i had on except he was wearing blue shirt.What should i do about this?I was told that several people that i heard of saw ghost just before they died.I think maybe the ghost is after me,and my entire family.Is god punishing me for not going to church and for not having lust inside me?What should i do people?I am not troll and i am not making this up.What your thought and solution to this problem?I am in my mom room when she came in asking me to stay with her because she saw ghost just earlier.
