Abstract: Lucid dreams are dreams in which the dreamer is aware that they are dreaming while the dream is still happening. Lucid dreaming has a wide range of potential benefits and applications in areas such as: scientific dream research; the treatment of nightmares; improvement of skills through rehearsal in the lucid dream environment; recreation; and, the use of lucid dreaming for problem solving and creative inspiration. Lucid dreaming is a learnable skill, and numerous lucid dream induction techniques have been developed. However, none of these techniques have been shown to be highly effective or reliable. The existing empirical literature on lucid dream induction suffers a wide range of limitations. Most studies have poor external validity and are based on small sample sizes consisting of self-selected lucid dreamers or university students. Other common issues include lack of random allocation to conditions, invalid or unreliable outcome measures, inconsistent operationalisation of lucid dreaming rates, and failure to measure variables that operationalise the way in which lucid dream induction techniques were practised. The lack of effective and reliable lucid dream induction techniques is the greatest obstacle to further research on lucid dreaming. Accordingly, the primary objective of the present thesis was to address this issue and conduct methodologically rigorous experimental research on lucid dream induction. The thesis begins with five chapters that provide background information on lucid dreaming. Chapter 1 provides a general introduction and overview of the thesis. Chapter 2 reviews developments in the history of lucid dreaming. Chapter 3 provides an overview of the phenomenology of lucid dreams. Chapter 4 reviews research on psychophysiological correlates of actions and experiences in lucid dreams. Chapter 5 provides a discussion of potential benefits and applications of lucid dreaming. Chapters 6, 7, 8, 9, and 10 present original research in the form of manuscripts that have been prepared for, submitted to or published by peer-reviewed academic journals. Chapter 6 presents a published review paper that investigated psychometric issues related to the tendency for retrospective measures of dream recall to yield substantially lower dream recall rates than logbook measures. Chapter 7 presents a published empirical study that addressed a range of psychometric issues raised in Chapter 6. Chapter 8 presents findings from a large experimental study (N = 169) on lucid dream induction; the National Australian Lucid Dream Induction Study (NALDIS). In this study, the Mnemonic Induction of Lucid Dreams (MILD) technique was shown to be effective for inducing lucid dreams. Reality testing was not shown to be effective. Chapter 9 presents findings from an extension of the NALDIS that investigated a novel lucid dream induction technique; the Senses Initiated Lucid Dream (SSILD) technique. Findings indicated that this technique was effective for inducing lucid dreams. Chapter 10 presents findings from a randomised, double-blind, placebo-controlled experiment (N = 100) that investigated the effects of B vitamins on sleep and dreaming. Findings indicated that vitamin B6 supplementation before bed significantly increased the amount of dream content recalled. The thesis concludes with a general discussion in Chapter 11.
