Dreams don't work unless you do 

The scientific study of dreams is known as oneirology .People are more likely to remember their dreams if they wake up during the REM phase( Rapid Eye Movement ).About 80% of neonatal and newborn sleep time is REM sleep, suggesting a tremendous amount of time dreaming.

According to Plato, dreams originate in the organs of the belly. Plato describes the liver in particular as the biological seat of dreams.

The average person has about 1,460 dreams a year. That’s about four per night. Modern research has shown that a sharp decrease in daily calories results in fewer nocturnal ejaculations in men and an overall decrease in the sexual themes of dreams.

During REM sleep, the flow of blood to the brain increases, as does the brain’s temperature. Additionally, both the penis and the clitoris become erect. Most of us dream every 90 minutes, and the longest dreams (30-45 minutes) occur in the morning.

Vitamin B complex (B6) and St. John’s Wort have been shown to produce more vivid dreams.

“Old Hag Syndrome,” or sleep paralysis, occurs in as many as 40% of all people. It happens when a sleeper wakes, recognizes his or her surroundings but is unable to move for as long as a minute. Sleep paralysis happens when one wakes up before their body completes the cycle of REM sleep.
