Darren Brown did a show in which he convinced a guy he was responsible for a murder by planting false memories. I thought it was a terrible thing to do for entertainment and hoped that it was lies and trickery with a convincing actor involved in it all.
Although Brown has done the show on christian tele evangelism to undermine faith in God and I think moved on to undermining faith in human nature now aswell.
On one or two occasions I've had insanely vivid dreams about having been involved in or having knowledge of or witnessing a murder, so vivid that when I woke I sort of believed they could be memories, I almost believed it was a repressed memory but I talked with my parents and they were like WTF, you'd know if you'd killed someone eejit. In time I realised that a lot of TV shows which featured this theme on around about the time I was "recalling" these memories from and I think that I'd internalised some of these as "truth".
