Intentionally awakening from sleep through lucid dreaming

Standard treatments for nightmares focus on waking activities, with consequences for subsequent sleep. An alternative strategy may be to provide people with a novel way to learn to end a nightmare by waking up. People typically think of sleep as a state that they cannot control, but there are exceptions to this rule. For example, the ability to select dream content in a lucid dream might allow one to wake up deliberately, thus countering the typical helplessness of nightmares. However, documented evidence that this strategy can work is lacking. Therefore, we recruited healthy participants to complete a task during their next lucid dream; they were instructed either to attempt to wake up or to clench their fists. In the former case, we offered several options for how to wake up. After sleep, participants responded to a detailed survey about their dream and their subsequent awakening experience. Relative to those who clenched their fists, participants who attempted to wake up from the dream by closing their eyes reported waking up sooner after task completion. Furthermore, higher levels of lucidity and lucid-dream skills while dreaming were correlated with a quicker wake-up time and reduced negative emotions. This research showed that people can succeed in waking up from sleep intentionally while lucid dreaming. Because lucid dreaming is trainable, training for waking up in this way could constitute a viable therapeutic approach to relieve nightmare suffering.
