An experiment that allows you to manipulate your dreams and reduce the frequency of nightmares by playing sounds during sleep

If you have a nightmare, you will feel sick when you wake up, and sometimes you wake up in the middle of the night because of a nightmare, so you don't want to have a nightmare as much as possible. A new study showed that ``playing sounds associated with positive images while sleeping can significantly reduce the frequency of nightmares.''

Nightmares Can Be Silenced With a Single Piano Chord, Scientists Discover : ScienceAlert

Nightmares can be triggered sporadically, but some people have nightmares on a regular basis. In addition to the survey results that 4% of adults suffer from chronic nightmares, research results have also been reported that nightmares and sleep disturbances increased during the pandemic of the new coronavirus infection (COVID-19). increase. Frequent nightmares increase the likelihood of waking up in the middle of the night and lead to poor sleep quality, which can have adverse effects not only mentally but also physically.

Image rehearsal therapy , a common treatment for people who have frequent nightmares, trains them to rewrite negative stories with more positive endings and tries to deal with nightmares by 'rehearsing' to see positive dreams. is what you do. Imagery rehearsal therapy has been reported to help reduce the frequency and severity of nightmares, but it is not always effective in all patients.

Therefore, a Swiss research team focused on the research results reported in 2010 that ``hearing a sound associated with a specific stimulus during sleep strengthens the memory of that stimulus''. By combining this method of ' targeted memory reactivation (TMR) ' with image rehearsal therapy, we conducted an experiment thinking that nightmares could be treated more effectively.

'There is a link between the types of emotions we experience in our dreams and our psychological well-being,' said sleep scientist Lampros Perogamvros, co-author of the paper. I thought I could help people by manipulating their emotions.'

The research team conducted a session on image rehearsal therapy after asking 36 subjects aged 20 to 35 who frequently have nightmares to describe their sleep and dreams for two weeks. This session was a lecture on how to perform image rehearsal therapy, and after returning home, the subjects were asked to practice image rehearsal therapy on their own at least once a day for the next two weeks. In addition, the subjects were divided into an 'experimental group combining

TMR with image rehearsal therapy' and a 'control group practicing only image rehearsal therapy'. , associated positive impressions of image rehearsal therapy with sounds.

During the two-week experimental period, all subjects underwent image rehearsal therapy for about 5 minutes each time they were awake, and went to bed wearing a headband that tracks their sleep at night. The headband was designed to play the piano chord C69 every 10 seconds when the subject entered REM sleep. According to the research team, the subjects followed the research procedures well and were very cooperative, such as performing image rehearsal therapy every day and wearing a headband firmly when sleeping.

At the start of the experiment, the control group had an average of 2.58 nightmares per week, while the experimental group had an average of 2.94 nightmares. However, as a result of image rehearsal therapy for two weeks, the frequency of nightmares in the control group decreased to an average of 1.02 times per week, and the experimental group only 0.19 times per week, and the frequency of happy dreams increased in the experimental group. About.

Furthermore, at 3-month follow-up, nightmares remained low in both groups, with an average of 1.48 nightmares per week in the control group and 0.33 in the experimental group. was These findings suggest that the use of TMR in addition to imagery rehearsal therapy may further improve nightmares reduction.

“We observed a rapid reduction in nightmares [with treatment] and more emotionally positive dreams,” Perogamvros said. It is very promising for research on emotional processing and the development of new treatments.'
