Can we induce lucid dreams? A pharmacological point of view
The phenomenon of lucid dreaming, in which an individual has the ability to be conscious and in control of his dreams, has attracted the public attention, especially in the era of internet and social media platforms. With its huge popularity, lucid dreaming triggered passionate individuals, particularly lucid dreamers, to spread their thoughts and experiences in lucid dreaming, and provide a number of tips and techniques to induce lucidity in dreams. Scientific research in the field of sleep and dreams has verified the phenomenon of lucid dreaming for decades. Nevertheless, various aspects regarding lucid dreaming are not fully understood. Many hypotheses and claims about lucid dreaming induction are yet to be validated, and at present lucid dreaming still lacks efficient and reliable induction methods. Understanding the molecular basis, brain physiology, and underlying mechanisms involved in lucid dreaming can aid in developing novel and more target-specific induction methods. This review will focus on the currently available scientific findings regarding neurotransmitters’ behavior in sleep, drugs observed to affect dreams, and proposed supplements for lucid dreaming, in order to discuss the possibility of inducing lucid dreams from a pharmacological point of view.
