Explanation: Theories of dreaming span scientific disciplines, from psychiatry and psychology to neurobiology. Some current theories suggest that dreaming is:

A component and form of memory processing, aiding in the consolidation of learning and short-term memory to long-term memory storage.

An extension of waking consciousness, reflecting the experiences of waking life.

A means by which the mind works through difficult, complicated, unsettling thoughts, emotions, and experiences, to achieve psychological and emotional balance.

The brain responding to biochemical changes and electrical impulses that occur during sleep.

A form of consciousness that unites past, present and future in processing information from the first two, and preparing for the third.

A protective act by the brain to prepare itself to face threats, dangers, and challenges.

There is not likely ever to be a simple answer or theory that explains the full role of dreaming in human life. Biological, cognitive, psychological—it’s very likely that dreaming may serve important functions in each of these realms.

Like sleep, dreams are vulnerable to disruption from problems with mental and physical health. There are a number of conditions (as well as medications) that may affect dreams, and that can make dreams more difficult and disturbing.

Depression and anxiety often are accompanied by nightmares, and the presence of nightmares may be an indication of the severity of depression. Research has found that among patients with Major Depressive Disorder, the presence of frequent nightmares is associated with suicidal tendencies. People who are depressed or anxious are more likely to have stressful, disturbing, or frightening dreams, sometimes in the form of recurring dreams.

There’s evidence that one type of drug commonly used to treat depression may alter dreaming. Selective Serotonin Uptake Inhibitors (SSRI) appear to affect dreaming in several ways. SSRI may decrease dream recall—the ability to remember dreams. This type of drug may intensify dreaming. SSRI may also lead to the presence of more positive emotions in dreams. Withdrawal from SSRI, on the other hand, may lead to nightmares and may also intensify dreaming.

Drugs and alcohol also can affect dreaming. Alcohol disrupts the normal, healthy sleep cycle and leads to fragmented sleep. Consuming alcohol heavily and too close to bedtime may alter and diminish the time spent in REM sleep. Studies show that alcohol-dependency is linked to dreams with more negative emotional content. Marijuana also disrupts and reduces REM sleep. Withdrawal from marijuana and cocaine has been shown in studies to induce strange dreams.
