your subconscious mind is active during dreaming, while the conscious, waking mind rests in sleep.
In response to the question about the brain, many different areas of the brain are active during dreams. The pons appears to stimulate dreaming, while the various sensory areas activate in dreams as if they were perceiving stimulation while awake. The cerebral cortex is particularly active during REM (Rapid Eye Movement) sleep. See the link to the Wikipedia article "sleep," below, for further information and references.
All of the brain participates in sleep. Different parts of the brain become active during different sleep stages and different types of dreaming. See attached link for further information.

Sleeping and waking depend on activities in the brain stem. Several areas of the brain seem to be involved in dreams and REM sleep, including the hippocamus and cortex. See attached links.

Dreams are believed to be a result of the brain's processing of experiences and emotions during sleep. During REM sleep, the brain is highly active, and areas responsible for emotions, memory, and processing visual information are activated. Neurotransmitters like serotonin and dopamine play a role in regulating dream functions.
Activation Synthesis Theory is a neurobiological theory of dreams, put forward by Allan Hobson and Robert McCarley in 1977, which states that dreams are a random event caused by firing of neurons in the brain. This random firing sends signals to the body's motor systems, but because of a paralysis that occurs during REM sleep, the brain is faced with a paradox.
Your dreams are the way your brain processes conscious thoughts into unconscious thoughts and symbols. There are books and information to interpret the dreams that you have to help you understand them.
Sleep seems to allow the brain to organise and prioratise memories. Dreams often refer to recent or important experiences you have had. It is the Mind that dreams are important to. The body survives well without sleep. Freud is generally discredited. JCF
Dreams are still shrouded in mystery. It is unknown where in the brain dreams originate, if there is a single origin for dreams or if multiple portions of the brain are involved, or what the purpose of dreaming is for the body or mind. Many people believe the Hippocampus is important in dreams, as it houses long term memory.
C. Dreams are a by-product of brain activity during sleep.
