Hearing an owl hoot at night depends on belief in supernatural signs. In many cultures and beliefs owl hooting at night time is an omen. That brings bad luck, bad health, or even death.
Owl hooting outside of your bedroom at night time means is that owl finds a nice place to hang around. There may be woods area nearby you and owl found food sources like voles. Owl likes to eat many other things like moles, frogs, rats, chipmunks, grasshoppers, and snakes, etc.
Furthermore, that is true owl used in witchcraft or cast a spell but then you must have some symptoms of black magic. Otherwise, this hooting has nothing to do with your personal.
Moreover, nighttime is a quiet time and if you are listing the hoot of an owl that means the same hoot can listen by other tens of people too. As I mentioned above it is only possible to connect it with one person if there are symptoms otherwise it is normal for an owl to hoot at night.
