No one knows why they’re here and for what. If you should be scared or not.WATCH OUT. There are not here to attack you only for shopping. For clothes, for food. Should you be scared? No. They might be dangerous but you can’t see them so there not able to hit you. But yes they are dangerous. But I don’t believe in them . Some are big, some are small .Some look creepy ,some look funny but you can’t see them.All they do is fly and do nothing. They probably have a Ghost Town. Somewhere. But you might be asking so why did they come to our place . I don’t know .
