![]() One theory about recurrent dreams is the threat simulation theory. Most of these related to athletic failure.Įlsewhere, a survey in which 30 women who were dealing with relationship violence described their dream experiences, half reported having weekly nightmares, and just over half had recurring dreams. In another study, 840 German athletes discussed distressing dreams that occurred on the nights before an important competition or game.Ībout 15 percent of the athletes reported having had at least one distressing dream before an important competition in the last 12 months. Just over half contained primary emotions other than fear. In a further 431 bad dreams, as opposed to nightmares, interpersonal conflicts were common. One in three of these nightmares contained primary emotions other than fear. bizarre and emotionally intense situations.Share on Pinterest Nightmares can cause distressing emotions and can be especially disturbing for children.Ī study that looked at 253 episodes described as “nightmares” found they frequently contained: ![]() The dreams that occur during these periods may differ significantly in both quality and quantity and probably result from different processes. One study has suggested that dreaming can happen during both REM and non-REM (NREM) sleep, but that different physiological processes underlie the dreaming at each stage. Does REM-sleep physiology explain the dream experience? Or is it not necessary to be in REM sleep for dreaming to occur? Researchers have different theories about the relationship between dreaming and REM sleep. As the night progresses, REM sleep periods increase in length, while deep sleep decreases. The first sleep cycles each night contain relatively short periods of REM and long periods of deep sleep. This paralysis is believed to be nature’s way of making sure we do not act out our dreams and thus prevents injury. This release of glycine effectively causes the body to become paralyzed. These motor neurons conduct impulses outward from the brain or spinal cord. The first REM sleep period usually occurs around 70 to 90 minutes after we fall asleep.ĭuring this phase, an amino acid known as glycine is released from the brain stem onto the motor neurons. Most dreams happen during a phase known as rapid eye movement ( REM) sleep. Each complete sleep cycle takes about 90 to 110 minutes. ![]() “This is the latest in a string of research showing that these experiences are very harmful,” she says, “not just for our ability to function during the day, but now, possibly, for our ability to sleep well at night, too.Share on Pinterest Why and how we dream remains something of a mystery. Weinstein says her research makes a broader point about mental health and should send a message to people who find themselves consistently feeling frustrated, lonely, incompetent or helpless. ![]() This suggests that day-to-day unmet needs really are influencing dreams, the authors say. Weinstein says it’s possible that the relationship could work in the opposite direction-that bad dreams could influence waking experiences-or that some people may simply be more likely to feel dissatisfied with their life and to experience recurrent bad dreams.īut people in the three-day study did report worse dreams after days when they reported more frustration, compared to days they felt more satisfaction. The study could not show that daily frustrations actually caused negative dream themes, only that there was an association. “Hopefully this is a first step in that direction, but we’ll need a much bigger sample before we can get there.” “I wish we could say there are certain assumptions you could make about someone who dreams about fire or who dreams about falling, but the evidence for that right now is still quite modest,” says Weinstein. They also asked 110 people to keep a dream diary and respond to psychology questionnaires over three days. To find out, they asked 200 people to complete a survey about how frustrated or satisfied they were with various aspects of their life, along with their most common recurring dream. People are more likely to be satisfied with their lives if they feel in control of their choices, good at what they do and closely connected to other people in their social sphere, says Weinstein, and missing out on these needs can lead to anxiety, depression and other mental health issues. Lead author Netta Weinstein, senior lecturer in psychology at the University of Cardiff in the U.K., wanted to find out if a lack of three basic psychological needs-autonomy, competence and relatedness-translated into disturbing dreams.
