"You are a house; you are haunted; and you just want to be left alone!
Why, when all you want is to be the sole occupant of your own body, do
stupid humans insist on coming to stay in you, either because they are
completely ignorant of what you are or because of it!?
You have a number of tricks and surprises at your command to help you
evict those unwanted guests. Your power is strongest at night, while at
dawn your power wanes. If you are up to the challenge you can have
solitude, but if you fail you will have to suffer occupants until the
next evening when your power returns and you can try again.
