Although some theorists have suggested that pain sensations cannot be part of the dreaming world, research has shown that pain sensations occur in about 1% of the dreams in healthy persons and in about 30% of patients with acute, severe pain.
The present study is the first to study pain dreams in patients with chronic pain.
A questionnaire was administered to 100 patients with chronic lower back pain and 270 controls.
The patients reported more pain dreams and more negatively toned dreams compared to healthy controls. In addition, patients reported more often that the dreamed pain persisted into waking state.
In patients, pain dreams might be instigated by actual pain whereas for healthy persons pain dreams might be pain memories (self-experienced pain and/or seeing persons in pain). Future research should clarify how pain is processed during sleep. As patients with chronic pain experience negatively toned dreams, it will be beneficial to ask chronic pain patients about their dreams and, if necessary, offer specific treatment options like imagery rehearsal treatment.
