Other Sections. For most people, dreaming is purely a mental activity: dreams occur in the mind while the body is at rest. But people who suffer from REM sleep behavior disorder (RBD) act out their dreams. They physically move limbs or even get up and engage in activities associated with waking. Some engage in sleep talking, shouting, screaming, hittting or punching.
There are, however, a great number of theories being explored. While some scientists posit that dreaming has no direct functionâbut instead is a consequence of other biological processes that occur during sleepâmany studying sleep and dreams believe dreaming serves a primary purpose. Theories of dreaming span scientific disciplines, from psychiatry and psychology to neurobiology.
