Raphael Vallat, a neuroscientist specializing in sleep and dream research at the University of California, Berkeley Sleep and Neuroimaging Lab, offers insights to Discover Magazine.

Vallat says dreaming “is one of the last frontiers in our understanding of the human mind.” And learning about dream recall – the why and how of remembering one’s dreams – may help scientists solve some of the mysteries of the dreaming mind.

Work by Vallat and others in the field has uncovered a number of interesting tidbits that seem to separate the dreamers from the so-called nondreamers, or the people seldom or never remember their dreams.
