Among 123 undergraduates, those who often speculated about their dreams or held theories about dream meaning were somewhat less likely to report nights without dream recall over a 10-day diary period. Women were more likely than men to speculate about and discuss their dreams.
A study of college students found no relationship between three MMPI personality scales (A, R, and Es) and the ability to recall and report dreams. Two groups of students were asked to produce written dream reports over several weeks, and those who did were compared with those who did not on the three scales. The results were not statistically significant, failing to confirm earlier research that had suggested such a link.
