The first laboratory evidence of lucid dreaming using machines was produced in the late 1970s by British parapsychologist Keith Hearne.
A volunteer named Alan Worsley used eye movement to signal the onset of lucidity, which were recorded by a polysomnograph machine.
Psychologist Dr Hearne’s original sleep-lab records and ‘dream- machine’ are on permanent display at the SCIENCE MUSEUM in London
