As with any obsessive interest, the UFO/alien viewpoint has attracted the attention of analyzers and categorizers.
The Gods Have Landed, edited by James Lewis, looks at the UFO-type groups that have become religionlike, like the Saucerians and George King of England, who suddenly heard a voice that announced, "Attention! You are to become the voice of the Interplanetary Parliament."
If you can't give a sociolgical analysis, you can always have a conference and transcribe the words of wisdom, as in UFOs and the Alien Presence. Of course, in many instances the "alien presence" is in the back of a turbulent mind.
