Dreams are successions of image, ideas, emotional and sensations occurring involuntarily in the mind during certain stages of sleep. Dream is a sleeping person's mind. Let us find out what research shows about the reasons that we dream, and read about theories of dream interpretation.

The human brain is a mysterious little ball of gray matter. Scientists have been performing sleep and dream studies for decades now, and we still aren't 100 percent sure about the function of sleep. It's also pretty commonly accepted among the scientific community that we all dream, though the frequency in which dreams are remembered varies from person to person.

Another theory is that dreams typically reflect our emotions. During the day, our brains are working hard to make connections to achieve certain functions. When posed with a tough math problem, your brain is incredibly focused on that one thing.

While scientists still do not know much about why or how we dream, some have suggested that we typically spend more than two hours dreaming each night. Many people experience their most vivid dreams during REM sleep, less vivid ...
... dreams occur at other times of the night.

In fact, everyone could dream every day. In the night, we may think some things, then, going to bed, we often dream it. It means that we think it, it will come true in the night. So, when we go to bed, we do not thing some things. It can influence our good sleep. While this theory suggests that dreams are the result of internally generated signals, Hobson does not believe that dreams are meaningless.
Another theory uses a computer metaphor to account for dreams. According to this theory, dreams serve to 'clean up' clutter from the mind, much like clean-up operations in a computer, refreshing the mind to prepare for the next day. One theory suggests that dreams are the result of our brains trying to interpret external stimuli during sleep.

Until someone proves or disproves one of these theories, or poses an alternate one, we are left at square one. Our knowledge as to what causes us to dream is limited to the fact that we do dream, and that dreams occur during the REM phase of sleep.
