Was just reading an article someone posted that said:

Experiments have shown that if sleepers are awakened as soon as REM starts, they enter REM sleep more rapidly the next time, and their REM is more intense. If the deprivation continues, they go into REM as soon as they fall asleep. It becomes impossible to deprive people of REM sleep without keeping them awake all the time. REM-deprived people can go into REM quickly in shorter naps.[/b]
Sounds like the recipe for a great WILD!
