Not about fertility but need advice

Elizabeth

We have been experiencing something weird. My 3 year old sleeps great everywhere but home. He wakes up crying almost every night. I always ask him why, he always says he was scared. So today he was talking about how he is brave so he wanted to watch Ghost Adventures. I told him if he is brave he can sleep alone and not cry for daddy. He tells me he is not afraid of ghosts just monsters like the dark man he sees at night that walks from our room to his and then to his baby brother’s room. Now I will tell you, on two occasions I have seen something at night. We never had an issue with this house, it was one of the things I loved about it, I have always been super comfortable and never saw anything. Can anyone give me advice to figure out what this is or make it stop?
