Request: experimental condition where subjects were instructed at bedtime to wake up at 03:00.

Surprise: experimental condition where subjects were instructed at bedtime to wake up at 08:00, but were unexpectedly woken at 03:00.

Success: when a subject could self-awaken at 03:00 ± 30 min.

Failure: when a subject could not awaken spontaneously at 03:00 ± 30 min.

astage 1 sleep; bS2: stage 2 sleep; cSWS: stage 3+4 sleep; dREM: stage rapid eye movement sleep; eTST: total sleep time; fWASO: wake after sleep onset. *p < 0.05.
