From an L.A. paper:
Los Angeles hypnotherapist Yvonne Smith said in May that more
than 30 people had joined her support group of those who say
they have been abducted by aliens. The group meets in Smith's
home once a month to discuss their problems in coping, for
example, with memories of aliens' sexual assaults, with aliens'
planting of tracking devices inside abductees' bodies, and with
abductees' methods of distinguishing between alien abductions
and abductions engineered by the CIA. Said Smith, "Because
(alien abduction) is controversial, there's still a certain
stigma attached to it."
