During lucid dreaming, people experience vivid perceptions and emotions that may have a psychophysiological impact after the person awakens. The goal of this research is to test whether it is possible to create pain during lucid dreaming and maintain it upon awakening. For this study, 151 volunteers completed a task in which they needed to achieve pain during lucid dreams (LD) and then wake up. They then checked whether the pain from the dream remained after they awoke, and, if so, they reported how long the pain lasted. Of the participants, 74% experienced pain during LD and 28% of them continued feeling the pain after waking. Our results may lead to new pain treatments and a better understanding of the nature of pain, LD, and hypnopompic hallucinations.

In lucid dreams (LDs), people can control the events of the dream plot and experience vivid perceptions. However, perception vividness in LDs is sometimes very low, thus preventing practitioners from fully experiencing the phenomenon or using it for a predetermined goal. The goal of this research is to test whether spinning in a LD can lead to an increase in the vividness of the perceived space. We had 123 volunteers spin while in a LD and then stop to check for changes in the degree of perception. For 46% of the volunteers, vividness became higher after spinning, and 30% of them (14% of all) reported having perceptions higher than in wakefulness. The result of this research may enhance the general understanding of the nature of subjective perceptions in LDs, which, in turn, will help in researching related phenomena and their applications.

Lucid dreams (LDs) are dreams in which people intentionally or unintentionally become conscious and take control of the dream plot, allowing them to experience different emotions and perceptions. The laws of physics do not apply to the LD world. As such, it supposedly lacks the limitations that we experience in everyday life.In the present study, we ask the following questions: Is this the case? Do we really have no limits in LDs? In this study, we investigated LD limitations on the possibility of flying. We instructed LD practitioners to fly while in an LD while performing no other movements (including jumping). That is, practitioners were to attempt to fly using only intention and thought. Then they were asked to report whether they succeeded, how much effort was required, and the duration of the flight. Most of the participants succeeded in flying while in an LD. Among those with successful results, almost everyone spoke about flying with little effort. We suggest that even within the context of LDs, some limitations prevent some practitioners from flying, which should be explored in future studies. The outcomes of our research deepen the general understanding of LDs and the capabilities of LD practitioners to realize different goals, even though LD does not follow physical laws.
