nightmares...why do we have them?

I had bad dreams Saturday night   And then on Saturday I also took a nap. I had another nightmare. Ugh.😱🙁😲 What is really up with nightmares? Why do we have them? 🤔

15 facts about nightmares 😱😱😱:

1. In the general population, 1 out of 20 people has nightmares every week. This ratio is much higher in those with psychiatric illness. For instance, three-quarters of those with PTSD have nightmares, and about half of those with borderline personality disorder have nightmares.

2. A small number of prospective studies suggest that nightmares could predict the onset of psychosis, PTSD, and sleep disturbances.

3. Nightmares often happen after a traumatic life event—such as that leading to PTSD—but onset can occur after any life stressor.

4. Increased levels of worry, hallucinatory experiences, and longer sleep duration have been found to be significantly linked to nightmare occurrence. This effect was sustained even after controlling for psychiatric illness, including negative affect, PTSD, and life stressors.

5. Worry appears to be the strongest predictor of nightmares. Additionally, people who are bigger worriers have worse nightmares. Worry could be a worse stressor because it primes your body for distress, preoccupation, and impairment.

6. The reason why people who sleep more experience more nightmares is because they stay in REM sleep longer. Duh!

7. The content of nightmares can be recalled in detail, unlike night terrors, which are parasomnias that occur in non-REM sleep.

8. In the ICD-10, nightmares can be coded as either nightmare disorder or PTSD.

9. People with PTSD also experience a higher prevalence of non-trauma-related nightmares. In other words, not all their nightmares are about the trauma experience; these people experience more nightmares overall.

A dream is a recollection of subjective experiences that happen during rapid-eye-movement (REM) sleep. On the other hand, nightmares are markedly dysphoric dreams with intense negative emotions which primarily manifest during late-night REM sleep.

10. Drugs like selective-serotonin reuptake inhibitors (SSRIs) can cause nightmares.

11. Genetics, life stressors, and mental health can all play a role in the occurrence of nightmares.

12. For the most part, psychotropic medications, like benzodiazepines and antidepressants, don’t help with nightmares.

13. Psychotherapy can help with nightmares. Examples include psychological desensitization, exposure therapy, imagery rehearsal therapy, and lucid dreaming therapy.

14. With imagery rehearsal therapy, the following happens:
The patient recounts a recent nightmare.
The patient imagines a new ending.
The new ending is rehearsed daily between 5 and 10 minutes for two weeks.

15. People with psychosis have bizarre and disorganized nightmares.
