The goal of the angel and the higher dimensional reality extraterrestrials is to connect you to your Source energy to connect you to your higher self to help you close the gap between where you are and where your higher self is vibrationally to help you close the gap between where you are  and where you want to be to guide you towards your own alignment, you could say fallen angels are a representation of man's own fear of separation of disapproval, of exile and of being cast out therefore they're more like a demon thought  form than an angel thought form, for this reason fallen angels are not actually considered angels
