Dreams can also refer to waking fantasies that we largely have control
over, such as daydreams. However, the scientific field of oneirology is
concerned with what happens when we sleep. "For a dream to be a
dream, it has to be an involuntary experience that occurs during the
Rapid Eye Movement, or REM, stage of sleep,' says neuropsychologist
Martin Dyson. "All other uses of the word dream fall outside the
domain of science." While all types of dreams are important, it is these
nighttime dreams that truly fascinate us.
