My Fiancé's Death in the House

A man died in the house who I would just call Robert, to protect his family's privacy. Doors to closets began to open, lights would turn on by themselves and my fiancé's dog began to growl at night. Instead of quiet footsteps, we began to hear running coming down the stairs to our bedroom door. One particularly scary experience was when I awoke late one night while my fiancé was sleeping. The hall light was on and was shining underneath the door. I also saw two shadows appear underneath the door, as if someone was standing in front of the door.
