Why do we dream? Is it our brains that makes us think? What is it?

can be entertaining, disturbing, or downright bizarre. We all dream, even if we don't remember it the next day. But why do we dream? And what do they mean, anyway?

What Are Dreams?

Dreams are basically stories and images that our mind creates while we sleep. They can be vivid. They can make you feel happy, sad, or scared. And they may seem confusing or perfectly rational. Dreams can happen at any time during sleep. But you have your most vivid dreams during a phase called REM (rapid eye movement) sleep, when your brain is most active. Some experts say we dream at least four to six times a night.

Lucid dreams

A lucid dream is one in which you know you’re dreaming. Research shows that lucid dreaming comes with a boost of activity in parts of the brain that are usually restful during sleep. Lucid dreaming is a brain state between REM sleep and being awake.

Explanation: There are many theories about why we dream, but no one knows for sure. Some researchers say dreams have no purpose or meaning. Others say we need dreams for our mental, emotional, and physical health.

Studies have looked into the importance of dreams to our health and well-being. In one study, researchers woke people just as they were going into REM sleep. They found that those who weren’t allowed to dream had:

More tension

Anxiety

Depression

A hard time concentrating

Lack of coordination

Many experts say dreams exist to:

Help solve problems in our lives

Incorporate memories

Process emotions

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

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.
