The 'dream-lag' effect: a 6-day temporal delay in dream content incorporation.
The temporal relationship between daily events and their incorporation into dreams was studied. In two experiments, a 6-day delay between event occurrence and dream incorporation was found. Moreover, variations in incorporation across a 7-day-period were found to follow a sinusoidal pattern. These results implicate dream incorporation in the learning consolidation functions of REM sleep.
