A controlled presleep experience was used in an attempt to trace waking experience in dreams. Dream reports were collected in the laboratory from 12 dreamers (half men, half women; half recallers, half nonrecallers), using the electrophysiological method of Dement and Kleitman. Following a baseline night, each dreamer was awakened on three consecutive nights during every REM period (rapid eye movement and Stage 1-ascending EEG pattern). Immediately prior to sleep on Night 3, four of the

... viewed an emotionally arousing film, four others viewed a s l ide sequence having the same content as the stressful film, and four others viewed an emotionally "neutral" film. Two independent judges, using Hall and Van de Castle's dream content analysis method and a tally system designed specifically for this study, failed to differentiate dreamers in the three groups on the basis of their dream content. Analyses of variance of dream content scores also failed to provide any evidence for differences among groups, recallers and nonrecallers, or nights. Some differences in dreaming style (e.g., total REM time, recallability) were noted. Limitations of the study and methodological problems were discussed. Posthoc analyses of dream reports with experimental situation content, dreamers' associations to their own dreams, and some clinical interpretations were included.
