THE MEANING OF DREAMS
Did you have any interesting dreams last night?
Our dreams come from a part of the brain that contains our thoughts and memories. A person can have up to six dreams a night, and each dream usually lasts from 10 to 40 minutes. Everyone dreams, but not everyone remembers their dreams. Most people dream in color, usually with sound. And we usually dream about ourselves and the people we know.
Why Do We Dream?
Alan Siegel is a scientist who studies dreams. "Dreams help us get in touch with our deeper feelings,” he says. "They can tell us a lot about ourselves, and can help us figure out problems.” Another scientist, Robert Stickgold, thinks dreams come from our memories. He believes we dream to remember, because memories are useful to the brain. Stickgold says the purpose of dreaming through these memories is to help us learn from the past.
Here are a few types of dreams and what people think they mean.
Dream 1: You Meet Someone While in Your Pajamas
Sometimes people dream that they meet someone they know while wearing their underwear (or nothing at all!). This dream may be the result of an embarrassing event in your life. Some people think we dream about embarrassing situations if our brains are trying to deal with an event in our own lives.
Dream 2: You're Flying
If you dream about flying, you are probably quite happy. This is a good period in your life. You may feel that other people see you as a leader.
Dream 3: You Didn't Study for a Test
This probably means you are worried about an important event coming in your life. If you're not prepared for the event, your dream may be telling you, "It's time to get to work!"

A.Dream 1: You Meet Someone While in Your Pajamas
B.Dream 2: You're Flying
C.Dream 3: You Didn't Study for a Test
