How is your mind connected to your dreams? Does this have anything to do with psychology?

Now there's a question Sigmund Freud would have appreciated! The physiologist, psychologist, medical doctor, and acclaimed father of psychoanalysis is credited with saying more than 100 years ago that dreams are the "royal road to our unconscious."

These days, dream interpretation draws lots of interest as we imagine what goes on inside our heads while we're sleeping — and what those little movies in our minds are really saying about us. Most people believe that dreams do have some deep meaning. Psychoanalysts suggest that our dreams represent unconscious conflicts, issues, and things that we want, but haven't expressed in straightforward language.

For example, you dream about being a passenger in a fast-moving car. Does that mean you'd like to head out for a quick vacation? Or is your subconscious trying to tell you to get behind the wheel and take control of your own direction and pace? Was the car bright red and were there 3 other passengers? Color and numbers also help shape meaning as you interpret the powerful symbols.

Remember that our brain activity changes when we sleep. Researchers think we have to catch some zzzzzzs in order for our brains to organize and store all the stuff we take in through our senses throughout the day. Dreams might pop up to give us some inside information about ourselves — just when we thought we had turned off that amazing computer in our heads!
