Many cultures regard dreams as having great
significance for the dreamer, either by revealing
something important about the dreamer’s present
circumstances or predicting his or her future. The
Austrian psychologist Sigmund Freud analysed the
dreams of his patients to understand their unconscious
needs and desires, and psychotherapists still make use
of this technique today. Freud believed that the primary
function of dreams was to wish fulfillment, or the idea
that dreaming allows us to act out the desires that we
must repress during the day. Although Freud focused on
the meaning of dreams, other theories about the causes
of dreams are less concerned with their content. One
possibility is that we dream primarily to help with
consolidation, or the moving of information into
long-term memory. Rauchs and Desgranges found that
rats that had been deprived of REM sleep, the sleep
stage in which dreaming occurs, after learning a new
task were less able to perform the task again than rats
that had been allowed to dream, and these differences
were greater on tasks that involved learning unusual
information or developing new behaviours.
