The Swansea University Sleep Laboratory investigates sleep, dreaming, and what happens when people are deprived of sleep. Undergraduate and postgraduate students in the Department of Psychology are involved in this work. Sometimes studies are run outside the lab, and we assess the sleep, or dream content, of people sleeping at home. Or we monitor people in the sleep lab, using electroencephalogram (EEG), and this can involve waking them up to collect dream reports. The laboratory is designed to be as comfortable and non-clinical as possible.
