When studying subjects like UFOs and occult phenomena, one tends to continually rediscover the interrelatedness of things. For instance, a modern gray alien is closely related to ancient descriptions of both angels and demons, and all three types of those paranormal entities often spill over into encounters with ghosts and other manifestations of communication from the departed. Some researchers, like Raymond Fowler and Dr. Kenneth Ring, make a definite connection between alien abduction and Near-Death-Experiences, arguing that the same otherworldly beings are present in both kinds of encounters and represent contact with creatures that exert a hopefully benevolent power over our very souls.
