Dream recall and content in long and short sleepers.

Abstract

Dream recall and content were studied in 10 female college students who habitually slept nocturnally for more than 9 hr. and in 7 who habitually slept less than 6½ hr. During 2 wk. 81 spontaneously recalled dreams were reported by the 7 short sleepers and 114 dreams by the 10 long sleepers. Of 9 dream content variables the 2 groups of sleepers differed significantly on only one and did not significantly differ in frequency of dream recall. It was suggested that in homogeneous groups of long and short sleepers length of sleep per se might be relatively unimportant in relation to dream reports and dream reporting, and other measured personality characteristics.
