Hi-tech dreamcatcher defeats sleep amnesia

When Adam Haar Horowitz took to the stage at a conference dressed as a lotus flower, he raised eyebrows. Then, when he started hitting computers and making gong noises, jaws dropped. He was acting out a dream he had recently had to illustrate how our night-time fantasies can influence our waking lives, and how technology can help us access them. It is a subject close to Mr Horowitz's heart. "Dreams are such a strange, murky, inaccessible space and there is so much poetry, metaphor and analogy in them," he told the BBC when it visited him at the Media Lab in the Massachusetts Institute of Technology.
