Morpheus had the power to enter dreams of the mortals to deliver messages from the gods. He first appeared in the epic poem Metamorphoses, written by the poet Ovid.

Sometimes, they’re simply a recollection of what happened earlier in your day.

    Dreams are most abundant during the REM stage of sleep or rapid eye movement. This is the deepest of the sleep cycle. When your eyes begin to move rapidly, your heart rate and breathing become inconsistent. Then your muscles experience some paralysis. This is some way of your mind to protect you from acting on your dreams physically. Some stages of REM sleep may last up to 30 minutes at a time. Some detailed dreams can last only for a few minutes but can be very rich.
