Hi, I would like to share an article about an online survey that was conducted some years ago. Participants were recruited here and on two other forums!
You can find the article here in the free online journal International Journal of Dream Research (IJoDR):
This is the summary: In a lucid dream the dreamer is aware of the dream state and can influence the dream content and events. The goal of this study was to investigate some applications of lucid dreaming. Our survey included 301 lucid dreamers who filled out an online questionnaire. The most frequent application (81.4%) was having fun, followed by changing a bad dream or nightmare into a pleasant one (63.8%), solving problems (29.9%), getting creative ideas or insights (27.6%) and practicing skills (21.3%). Women used lucid dreams significantly more often than men for both work on nightmares and problem solving. Our results show that lucid dreams have a great potential for improving one’s life in different ways. More research is needed to illuminate the possibilities of lucid dreaming, specially in the fields of nightmare treatment and practicing motor skills.
