Flying saucers, UFOs, extra-terrestrial life - most people think it is all fiction. But for some it is all too real and an international conference was held in Perth in Western Australia to discuss the "hidden truths", information that a so-called secret government is withholding from the public. Conference organiser Mary Rodwell has counselled 800 people in Perth who say they have been contacted by non-humans. Ms Rodwell says most of these experiences seem to have occurred when the individual is relaxed, like when they are about to go to sleep. "I mean beings from other planets, but I also say that we think some of the beings may be what's known as inter-dimensional as well," Ms Rodwell said. "So I mean it's a very hard one to explain but it's like not all of them come from this dimension." So what kinds of experiences do people have with these beings?"The classic X-Files is the bright lights in the room, not being able to move, feeling a presence or presences around you, obviously feeling frightened and frozen in their beds, they feel like they're paralysed, often there's a sense of a buzzing sound around them, and sometimes they have a feeling of going through walls or, and having certain procedures done on them on the craft," Ms Rodwell said. But given that a lot of these experiences have happened in relaxed states, could it be possible these are manifestations of the mind?
