The present study aimed to examine the reliability of eight-point scales for measuring lucid dream and nightmare frequencies. The scales were administered twice (with a four-week interval) to 93 sport students. A re-test reliability for the lucid dream frequency was found r=.89 (p&lt;.001) and for the nightmare frequency r=.75 (p&lt;.001). Both eight-point scales appear to be reliable measures for assessing individual differences in lucid dream and nightmare frequencies.</p> ER -
