Dreams

What is dream?
Is it just a flower bed?

Nope, our brain creates dreams through random electrical activity. About every 90 minutes, the brain stem sends electrical impulses and the analytic portion of the brain tries to make sense of these signals.

Dreams are not meaningless.

In fact, the way our brains choose to "analyze" the random and discontinuous images might tell us something about ourselves.

We can learn from our dreams.

A dream represents the organization of thoughts and feelings that are collected throughout a day into a particular structure, which you can
later access and learn from.

Lucid dreaming is about being able to control your dreams—where your "dream self" obeys the waking mind's vision.

Some researchers believe lucid dreams can help people in many ways, including developing creativity and coping with grief.

When do dreams happen?

Most dreams happen during the REM (rapid-eye movement) phase of sleep, the stage of sleep when our brains are most like a wakeful state.

Transfer of information from short- term to long-term memory
REM sleep—the deep sleep where the most powerful dreaming occurs—is also when a person can transfer information from short-term memory to long-term memory.
