The study aims to examine whether lucid dreaming can help treat depression. Subjects with depression will be divided into four groups. Two groups will receive lucid dreaming training while the other two will not. One group receiving training will also take antidepressants. Subjects will keep dream logs and be evaluated after three months to see if lucid dreaming improved their mood, behavior, and depression symptoms. The researchers hypothesize that by gaining control over dreams through lucidity, subjects can alter nightmares and improve sleep, which may help treat their depression.
