What's the scariest experience you had in life???

I know this sounds crazy but my husbands deceased wife lives here with us. She has done some damage to the house. Anytime i or my husband make changes the she does not like she will let us know. She has pulled a speaker out of the ceiling. She has pulled a hanging macrame glass table off the hook that is into the ceiling. But left the hook. Thing disappear and reappear. Doors will open and close. And she messes with the thermostate. And many more things. I have a parrot and all the sudden he will go crazy and attack the air around him. I have done a lot of remodeling of the house and some to her approval some not. But i promise she will let me know which ones she does not like
