HERE'S YOUR ANSWER⬇️⬇️⬇️

Dreams are basically stories and images our mind creates while we sleep. Dreams can be vivid. They can make you feel happy, sad, or scared. And they may seem confusing or perfectly rational.

Dreams can occur anytime during sleep. But most vivid dreams occur during deep, REM (rapid eye movement) sleep, when the brain is most active. Some experts say we dream at least four to six times per night.

Why Do We Dream?

There are many theories about why we dream, but no one knows for sure. Some researchers say dreams have no purpose or meaning and are nonsensical activities of the sleeping brain. Others say dreams are necessary for mental, emotional, and physical health.

Studies have shown the importance of dreams to our health and well-being. In one study, researchers woke subjects just as they were drifting off into REM sleep. They found that those who were not allowed to dream experienced:

Increased tensionAnxietyDepressionDifficulty concentratingLack of coordinationWeight gainTendency to hallucinate

Many experts say that dreams exist to:

Help solve problems in our livesIncorporate memoriesProcess emotions

If you go to bed with a troubling thought, you may wake with a solution, or at least feel better about the situation.

Sigmund Freud believed dreams are a window into our subconscious. He believed they reveal a person's:

Unconscious desiresThoughtsMotivations

Freud thought dreams were a way for people to satisfy urges and desires that were unacceptable to society.

Perhaps there is merit with all these theories. Some dreams may help our brains process our thoughts and the events of the day. Others may just be the result of normal brain activity and mean very little, if anything. Researchers are still trying to figure out exactly why we dream.

What Are Lucid Dreams?

Have you ever had a dream where you knew you were dreaming during your dream? This is called a lucid dream. Research has shown that lucid dreaming is accompanied by an increased activation of parts of the brain that are normally suppressed during sleep. Lucid dreaming represents a brain state between REM sleep and being awake.

Some people who are lucid dreamers are able to influence the direction of their dream, changing the story so to speak. While this may be a good tactic to take, especially during a nightmare, many dream experts say it is better to let your dreams occur naturally.
