It won't hurt you. Some people are aware of this, but not many. It is most likely your guardian angel looking out for you and to protect you. They don't really exist, but people who have a sort of sixth sense create them without knowing they do. You may well be a deep and psychic person.
They are similar to the brownies in your home that are full of mischief. They will hide your comb and make you search everywhere. If you tell them to put it back, you will find it exactly where it should be. if you don't tell them, they will put it back the following day. Usually after you've just bought a new one.
