New Insights on Source of Recurring Bad Dreams

New Insights on Source of Recurring Bad Dreams

Emerging research on dreams suggests repeated bad dreams may reflect psychological frustrations associated with failure to adapt to challenging situations.

Netta Weinstein of the University of Cardiff, is the lead author of an article, “Linking Psychological Need Experiences to Daily and Recurring Dreams”, published in the journal Motivation and Emotion.

She believes unmet daily psychological needs for autonomy, relatedness, and feeling competent can lead to bad dreams. Moreover, the frustrations can cause the dream to be recurring and for people to analyze their dreams negatively.

Dreams and their interpretation have been investigated since the days of Jung and Freud. However, the research done by Weinstein’s team is the first to explore whether people’s daily frustration or fulfilment of psychological needs plays out in their dreams.

The researchers conducted two studies. In the first, 200 people were asked to reflect on their most common recurring dream. The second study analyzed the entries that 110 people made over a period of three days in “dream diaries”.

This was done to explore whether experiences related to psychological needs in waking life are related to the deeper level of processing that dreams provide, and that so-called “bad” dreams might be “left-overs” of poorly or even unprocessed daily experiences.

“Waking-life psychological need experiences are indeed reflected in our dreams,” says Weinstein.

The results from both studies show that frustrations and emotions associated with specific psychological needs influence the themes that will occur in people’s dreams.

Participants whose so-called psychological needs were not met, either more enduringly or on a day-to-day basis, felt more frustrated. They reported having more negative dream themes such as frightening dreams, or ones in which sad or angry emotions surfaced.

When asked to interpret their own dreams, they tended to do so using more negative words. Participants whose psychological needs were met were more likely to describe their dreams positively.

“Negative dream emotions may directly result from distressing dream events, and might represent the psyche’s attempt to process and make sense of particularly psychologically challenging waking experiences,” explains Weinstein.

People who were frustrated with their daily situation tended to have recurring dreams in which they were falling, failing or being attacked. According to Weinstein, recurring dreams may be more sensitive to distressing psychological experiences that a person still needs to process.

“Researchers and theorists have argued that recurring dreams challenge people to process the most pressing problems in their lives, and these may be thought to result from their failure to adapt to challenging experiences.

“As such, dream content may be more affected by enduring need-based experiences,” says Weinstein.

Higher Risk of Mental Illness Among Daughters of WWII Evacuees

Higher Risk of Mental Illness Among Daughters of WWII Evacuees

Mental illness related to early childhood trauma may be passed from generation to generation, according to new research appearing in JAMA Psychiatry.

The study, which looked at adults whose parents had either evacuated or remained in Finland as children during World War II, found that daughters of female evacuees had the same high risk for mental health disorders as their mothers, even though they had not faced the same trauma.

The study was conducted by researchers at the National Institutes of Health, Uppsala University in Sweden, and Helsinki University in Finland.

Although the study did not determine why this risk persists across generations, possible explanations include changes in the evacuees’ parenting behavior resulting from their childhood trauma or epigenetic changes — chemical alterations in gene expression, without any changes to underlying DNA.

“Many studies have shown that traumatic exposures during pregnancy can have negative effects on offspring,” said study author Stephen Gilman, Sc.D., of the Division of Intramural Population Health Research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

“Here, we found evidence that a mother’s childhood traumatic exposure — in this case separation from family members during war — may have long-lasting health consequences for her daughters.”

From 1941 to 1945, approximately 49,000 Finnish children were evacuated from their homes into Swedish foster homes in order to protect them from bombings, malnutrition and other hazards during war with the Soviet Union.

Many of these children were only preschool age. These children faced the trauma of separation from their families, adapting to their new foster families, and in many cases, learning a new language. Upon their return, many of these children experienced the additional stress of re-adjusting to Finnish society. On the other hand, thousands of Finnish families chose not to evacuate all their children and often kept some at home.

For the study, the researchers compared the risk of being hospitalized for a psychiatric (mental health) disorder among offspring of the evacuees to the risks of psychiatric hospitalization among the offspring of the siblings who remained with their parents.

Studying both groups allowed the researchers to compensate for family-based factors that can contribute to mental health problems and to focus instead on the evacuees’ wartime experience.

Findings from a previous study had shown that children who had been evacuated were more than twice as likely to be hospitalized as an adult for a psychiatric disorder than their female siblings who remained at home.

For the current study, the researchers linked the records of more than 46,000 siblings born between 1933 and 1944 — to those of their offspring, more than 93,000 individuals born after 1950. Of these, nearly 3,000 were offspring of parents who had been evacuated to Sweden as children, and more than 90,000 were offspring of parents who remained in Finland during the war.

The findings show that female evacuees and their daughters were at the greatest risk for being hospitalized for mood disorders, such as depression and bipolar disorder. In fact, the daughters of evacuees faced more than four times the risk of hospitalization for a mood disorder, compared to the daughters of mothers who stayed home — regardless of whether their mothers were hospitalized for a mood disorder.

The researchers did not find any increase in psychiatric hospitalizations for the sons or daughters of males who had been evacuated as children.

While the study could not determine why the daughters of female evacuees faced a greater risk, one possibility is that the evacuation trauma may have impacted their mental health in ways that influenced their parenting style.

Another possibility is that the evacuee experience resulted in epigenetic changes. For example, previous research has shown that Holocaust survivors have higher levels of compounds known as methyl groups bound to the gene FKBP5 and have passed this change on to their children. This higher level of methyl groups appears to alter the production of cortisol, a hormone that regulates the stress response.

“The Finnish evacuation was intended to protect children from the many harms associated with the country’s wars with the Soviet Union,” said study co-author Torsten Santavirta, Ph.D., of Uppsala University. “Our observation of long-term psychiatric risk that reached into the next generation is concerning and underscores the need to weigh benefits as well as potential risks when designing policies for child protection.”

The researchers conclude that more studies are needed to understand how the experience of war impacts the mental health of parents and their offspring and to develop interventions to help families affected by armed conflict.
