; Sleep Phenomena
: '''Jet Lag''' → When your internal clock (SCN) is out of sync with the local sun (Process C).
: '''Social Jet Lag''' → The disconnect between your natural chronotype (Night Owl) and the demands of society (9-to-5 jobs).
: '''Lucid Dreaming''' → Becoming aware that you are dreaming during REM sleep; a state of "mixed" consciousness.
: '''The First Night Effect''' → When sleeping in a new place, the left hemisphere of the brain stays "partially awake" to monitor for danger.
