Results of lucid dreaming treatment revealed that the nightmare frequency of the treatment groups had decreased. In another study, Spoormaker, Van den Bout, and Meijer (2003) investigated lucid dreaming treatment for nightmares by testing eight subjects who received a one-hour individual session, which consisted of lucid dreaming exercises.

A little over half the population has experienced a lucid dream at least once in their lives, according to a 2017 study, and about 20 percent of individuals experience lucid dreams at least once a ...
A lucid dream is one in which the dreamer is aware that they are dreaming. They are able to exert some or a complete control over the dream's characters, narrative and/or environment. Early references to the phenomenon are found in ancient Greek texts.
