More on haunted houses

I found out that I sold a haunted house a while ago. The homeowner told my husband that one night before going to bed he asked his wife if everything was off and she told him yes, so they went to bed. In the morning, the husband saw that a candle was burning in the kitchen so he blew out the candle and woke up his wife and asked her if she left a candle burning. The wife said no, I never had a candle going! And she went back to sleep. When she woke up the candle was burning again! The couple also say that they see a shadow every now and then of a little boy on the wall. After the experience with the candle, they started asking the neighbors about the previous owners. Come to find out that a little seven year old boy that lived there got hit by a car and died.
