| Summary: | The possibility that a positive correlation between nightmare frequency and hypnotic susceptibility reported by Belicki and Belicki (1986) was an artifact of administering a sleep questionnaire in the context of a hypnosis experiment was tested in the present study. Measures of vividness and absorption were also administered. Forty subjects, twenty of whom were told that the measures were related to hypnotic responding, completed the questionnaires immediately prior to hypnosis. Twenty other subjects, who completed the questionnaires in contexts unrelated to hypnosis, were later hypnotized. The hypothesis that context of administration of the questionnaires influenced the relationship between the measures and hypnotic susceptibility was not supported. Replication using a larger sample was recommended.
