Hey Pandas, What Was Your Most Inexplicable Experience?

Usually at night when I am in bed I hear strange noises because my house is old and also historic. So one night before I went to bed ( It was like ten or eleven ) I hear this weird noise and I thought it was coming from the fridge right outside my bedroom but I walked outside and it was turned off. I was confused and walked back into my bedroom finding my closet and bathroom door were open even though I left them closed. That night all I heard was footsteps throughout my whole house. It was creepy.
