Because REM sleep is associated with dreaming, on the one hand, and eye movement, on the other, it has been tempting to assume that each movement of the eye is associated with
a specific dream image.
When we move our eyes in REM sleep, according to the study,
specific brain regions show sudden surges of activity that resemble the pattern that occurs when we are introduced to a new
image — suggesting that eye movements during REM sleep are responsible for resetting our
dream «snapshots.»
