my ghost friend! HELP

🌹
Any of you have any idea why our little ghost friend doesn't show up when my husband is home? Only when I'm home alone?
He is usually very quiet, doesn't move anything but last night I heard a cabinet shut in the kitchen.. I blamed it on our new neighbors, it was after 1am. This morning I'm in the bathroom and I hear the fridge door open! The door to our fridge always shuts by itself, the door was staying open like someone was holding it. Right when I started to walk towards the kitchen, the door started to close. My husband works nights and swears I'm crazy because he has never seen our little ghost friend. 
I catch our dog looking into the kitchen/dining area all the time. Sometimes the hair on his neck will stand up 🤷🏻‍♀️
Tell me some stories or give me advice!!
