PHNOM PENH, Sept 5, 2007 (AFP) - 'I always have nightmares about being chased by something black, a shadow,' says doctor Sotheara Chhim, describing the aftermath of peering into the dark places most Cambodians are trying to forget.

'It is not something clear, but it is probably relevant to the Khmer Rouge,' says Chhim, one of only 26 psychiatrists providing care for a rising tide of Cambodians who are no longer able to cope with the damage caused by the brutalities of the past.
