Disinfonauts may be interested in this TV show which suggests that the UK harbours a large subculture of people who claim direct contact with Extra Terrestrials, not unlike the one in the US.
It profiles a group called A.M.M.A.C.H. who run a helpline for alien contactees.
From the Channel 4 website:
Anomalous Mind Management Abductee Contactee Helpline, or AMMACH, the 999 for people who believe they have been victims of alien abduction.
The film follows some of the 100 members who use the helpline, including Simon, a town councillor who believes that in addition to his earthbound wife he has a family of alien children with an alien lover.
There’s also Chantelle, a housewife who’s been abducted thousands of times and wants her encounters to stop.
Marie is an accountant who believes that her DNA has been altered and that she may be part alien.
