Bat is about rebirth. Bat can see in the dark – and so he is a little scary to some folk. Folk are superstitious about bat and owl, because they can see in the dark – bat and owl people know secrets, which is the source of most superstitions about them – folk don’t want their secrets known! Bat (except for flying fox) also uses echolocation to find his food – keen sense of hearing, and navigation.
The bat folds up in the daytime, and flies at night. The folding of his wings is like a womb, from which he is reborn every day at dusk. He is a transformational animal, and you are on the path to new insights.
