Dream Recall: State or Trait Variable? Part I: Model, Theories, Methodology and Trait Factors

Abstract
The aim of the present article is to carefully review the research carried out hitherto regarding factors influencing dream recall. With respect to the hypotheses explaining the variation in dream recall frequency (DRF) and a model of the dream recall process, the empirical data has been divided into two groups, trait factors and state factors. In the first part of the article the studies on the influence of trait factors are reviewed. The second part incudes data concerning state factors, new empirical data and some final conclusions. State factors such as nocturnal awakening and focusing on dreams in the morning and trait factors such as fantasy life, creativity and visual memory play a major role in explaining variability in dream recall.
