"Weird things start to happen when you stare into someone's eyes for 10 minutes"

"A psychologist based in Italy says he has found a simple way to induce in healthy people an altered state of consciousness – simply get two individuals to look into each other's eyes for 10 minutes while they are sitting in a dimly lit room. The sensations that ensue resemble mild "dissociation" – a rather vague psychological term for when people lose their normal connection with reality. It can include feeling like the world is unreal, memory loss and odd perceptual experiences, such as seeing the world in black and white."

"Giovanni Caputo recruited 20 young adults (15 women) to form pairs. Each pair sat in chairs opposite each other, one metre apart, in a large, dimly lit room. Specifically, the lighting level was 0.8 lx, which Caputo says "allowed detailed perception of the fine face traits but attenuated colour perception." The participants' task was simply to stare into each other's eyes for 10 minutes, all the while maintaining a neutral facial expression. A control group of a further 20 participants also sat in a dimly lit room in pairs, but their chairs faced the wall and they stared at the wall. Beforehand both groups were told that the study was going to involve a "meditative experience with eyes open."" (read the whole thing)
