The collection of home and laboratory dreams by means of an instrumental response technique.

Abstract

A new technology for dream collection, an instrumental response technique, was used to record dreams in both the sleep laboratory and in the subjects' own homes. This technique employs a switch attached to the sleeper's hand. The subject is asked to depress the switch to signal the presence of dream experiences during sleep. Comparisons were made between dream reports from home and laboratory collected under uniform sampling conditions. Differences in signalling frequency between REM and NREM sleep were noted. The effect of training to identify dreams by awakenings from REM when no spontaneous signal was given was examined. Results showed that: 1) There were no significant content differences between home and laboratory dreams when the dreams were collected in the same way. 2) This technique is useful in identifYing dreams taking place in sleep other than REM which has been difficult to do in the past. 3) Subjects trained to identify dreams performed better than untrained subjects.

A review of mentation in REM and NREM sleep: “Covert” REM sleep as a possible reconciliation of two opposing models

“…The present REM recall estimate of 81.9% also compares favorably with both (1) an estimate of 83.3% from over 200 subjects and 2,000 REM sleep awakenings (Dement 1965) and 2 (Armitage 1980;Armitage et al 1992;Cavallero et al 1992;Goodenough et al 1965a;Herman et al 1978;Pivik & Foulkes 1968). On average, recall from these stages is equal to that of stage 2 sleep; a tally of eight studies (Cavallero et al 1992;Fein et al 1985;Foulkes 1966;Lloyd & Cartwright 1995;Moffitt et al 1982;Pivik 1971;Pivik & Foulkes 1968;Rotenberg 1993b) revealed an average recall rate of 52.5 Ϯ 18.6%. The average stage REM recall rate in these studies was 82.2 Ϯ 8.1%.…”

Dreaming as a Mood-Regulation System

“…68 The relevance of dream health to waking physical and mental health has been pointed out in a recent study. Collecting dreams in the laboratory is costly and not usually covered by insurance.…”
