UFOs Under Investigation: Alien Abductions Documentary

The terms alien abduction or abduction phenomenon describe "subjectively real memories of being taken secretly against one's will by apparently nonhuman entities and subjected to complex physical and psychological procedures". People claiming to have been abducted are usually called "abductees" or "experiencers".

Due to a paucity of objective physical evidence, most scientists and mental health professionals dismiss the phenomenon as "deception, suggestibility (fantasy-proneness, hypnotizability, false memory syndrome), personality, sleep paralysis, psychopathology, psycho-dynamics [and] environmental factors" Skeptic Robert Sheaffer sees similarity between the aliens depicted in early science fiction films, in particular, Invaders From Mars, and some of those reported to have actually abducted people.
