5 Reasons Why You Dream

Information Processing and Memory

Research already supports the claim that sleep is fundamental to a well functioning mind and memory. However, some suggest that the key to memory consolidation lies not within a few hours of rest, but in the dreams we have instead.

Most dreams incorporate recent events and occurrences we've experienced. Perhaps you dreamt of that traffic accident you saw last week, or you might have reflected on your weekly trip to the grocery store. These kinds of dreams might actually be your brain processing and organizing the conscious and unconscious stimuli it receives throughout the day. After your daily memories have been consolidated by your dreams, your brain gets a chance to refresh itself, in a sense; dreams are the brain's way of "rebooting the system."
