It’s a very useful ability to have if you’re worried the human might have heard you. You’ll be able to ‘hear’ if they’re considering seeking you out or if they just wrote the sound off as just the house settling.
Also, if you get bored and are strong enough, you can always get into someone’s head and make them think they’re hearing voices. Get them to leave out a snack or two for you if you need some food for the week.
