Some psychologists claim that dreams are the firing of neurons during a state of rest, while others suggest that dreams are a window into our subconscious. Other’s say that dreams prepare us for future challenges and are an adaptive survival mechanism. Most dreaming happens during REM (rapid eye movement). During this time, the brain is in an active state, but you are in a state of paralysis. When in a dream state, the emotional side of the brain is more active than the logical side, which helps explain why dreams can be emotional. REM dreams have been proven to be more vivid and fantastical. Dreaming can be used as a coping mechanism. When we are under a lot of stress we tend to remember our dreams. A recent study showed that lucid dreaming may be associated with psychological well-being.
