A recurring dream is a dream which is experienced repeatedly over a long period. They can be pleasant or nightmarish and unique to the person and their experiences. There is evidence that recurring dreams can be a symptom to help diagnose some psychological disorders.
Common themes in recurring dreams
Through psychological analyses and studies, some recurrent themes have been identified. These include dreaming of being chased and pursued, which has been repeatedly demonstrated as being the most frequently experienced recurrent theme. The following themes below have been found to contribute to more than half of recurring dreams:
- Difficulties with house maintenance
- Teeth falling out - Freud believed that if a woman had a recurring dream of her teeth falling out that she unconsciously longed to have children. He believed that if a man had this dream he was afraid of castration.
- Discovering new rooms in a house - Freud believed that houses represented bodies. Others thought finding new rooms represented the dreamer finding out new things about themselves or of their own potential.
- Losing control of a vehicle
- Being unable to find a toilet
- Having the ability to fly
The subjects of recurring dreams do vary. The following examples are also common:
- Being held down or otherwise unable to move (compare sleep paralysis)
- Nakedness in a public place
- Being held back in school or failing a test
- Losing the ability to speak
- Escaping or being caught in a tornado/storm
- Drowning, or otherwise not being able to breathe
- Finding lost items
- Unable to turn on the lights in one's house
- Being with a significant other.
Psychological disorders associated with recurring dreams
- Post Traumatic Stress Disorder: People suffering from post-traumatic stress disorder can often suffer from recurring dreams. These dreams are thought of as chronic nightmares that act as a symptom of PTSD. A study found that the degree of trauma had a positive relationship to distress related to dreams 
- Anxiety: Evidence suggests that recurrent dreams occur during times of stress and once the problem has resolved they will cease to recur.
- Obsessive compulsive disorder
Possible explanations for recurring dreams
- Threat simulation theory - This theory was proposed by Antti Revonsuo and states the biological function of dreaming is to simulate threatening events and then rehearse threat avoidance behaviors. However, this theory has come with mixed reviews. Zadra et el. found in a study on this theory that 66% of recurrent dreams contained at least one threat. For the most part, these threats involved danger and were aimed at the dreamer themselves. In contrast however, they also found that less than 15% of recurrent dreams involved realistic situations that could prove critical to ones survival. They also found that the dreamer usually did not succeed at fleeing the threat. These provide mixed support for the theory originally proposed by Rensuo.
- Gestaltist dream theory - This theory views recurrent dreams as representing the person's current state of psychic imbalance. By bringing this imbalance to consciousness through the recurrent dream, it is possible for the person to restore their self-balance 
- Freud believed that recurrent traumatic dreams showed expressions of neurotic repetitive compulsions.
- Jung believed that recurrent dreams played an important role in the integration of the psyche.
- Culturalist dream theory, brought to light by Bonime in 1962, holds that recurrent dreams represent a lack of positive change or development in a person's personality.
Treatment methods for recurring dreams
- Practicing relaxation techniques and imagery exercises before going to sleep is a popular treatment suggestion. By imagining the dream and an intentional task to be carried out during the dream, the person will remember to carry out that task when they are actually dreaming. Then, when it occurs in the dream it will act as a prerehearsal cue in order to remind the person that they are dreaming, where they then can interact with the dream imagery. Once this is achieved, they can consult with their therapist the best way to modify their recurrent dream to make it less traumatizing. There are several different proposals suggested to go about doing this.
- Confront and conquer the feared scene, suggested by Garfield in 1974.
- Alter a small aspect of the dream, suggested by Halliday in 1982.
- Have the dream ego engage in conciliatory dialogue along with hostile dream figures, suggested by Tholey in 1988
