<unk>  (PAS), also sometimes called Post-abduction Stress<unk>  (PASS), is a collection of symptoms commonly reported by persons who claim they have been the victim of an alien<unk> . The<unk>  is not officially recognized by the American Psychiatric Association, the American Psychological Association or by equivalent professional associations in other nations. PAS shares many symptoms with the officially recognized Post-traumatic Stress Disorder but is not the same. PAS does not refer to all<unk> s, e.g., a criminal kidnapping, but only those allegedly involving "alien<unk> s".
Various researchers report that many of the symptoms reported in PAS situations are similar or identical to reports of encounters with demons or other paranormal phenomena. (Catoe 1978; Vallée 1988; Alnor 1992; Ross 2002)
