 note = {The purpose of the present study was to examine the frequency and intensity of typical themes of nightmares in Japanese undergraduates and their relationship to nightmare distress, trait anxiety, depression, and fantasy proneness. In a preliminary survey, open-ended descriptions of nightmare themes were collected from 128 undergraduates. The descriptions were classified into nine categories using the KJ method. In the main survey, the frequency and intensity of ten themes of nightmares, representing the ten categories identified in the preliminary survey, were measured using a Likert scale（the Typical Nightmare Questionnaire）. Two hundred and eighty seven undergraduates, ranging in age from 18 to 22 years, were administered a questionnaire consisting of five scales: the frequency of nightmares and dream recall, the Nightmare Distress Questionnaire （NDQ-J: Okada & Matsuda, 2014）, the Japanese version of the State-Trait Anxiety Inventory（STAI-t: Shimizu & Imaei, 1981）, a Self-rating Depression Scale（SDS: Fukuda & Kobayashi, 1971）, and the Creative Experience Questionnaire（Okada, Matsuoka & Todoroki, 2004）. A factor analysis of the frequency and the intensity of the 10 themes revealed a two-factor structure: nightmares involving harrowing situations and nightmares involving relationship anxieties. The frequency and intensity of nightmares involving harrowing situations related to scores on the STAI, SDS, NDQ, and CEQ, but the frequency and intensity of nightmares involving relationship anxieties were only related to scores on the STAI and SDS.},
