10 steps to ease your nightmares and improve sleep

Nightmares, Martin said, occur during rapid eye movement sleep, the phase during which our muscles relax and we dream. Waking up during REM sleep enables recollection of the dream and resulting distress.

"One of the most effective ways to treat nightmare problems in adults is actually to get them sleeping more soundly (so) they wake up less often," Martin said.

Alcoholic beverages can induce restlessness and awakenings throughout the night — potentially helping you remember nightmares, Martin said.

"A lot of people use alcohol as a way to wind down and feel sleepy at the end of the day, but it's really not the right solution," she added. Instead, try herbal teas and other beverages conducive to sleep. If drinking was the only part of your relaxation routine, chat with your partner or read instead.

Snacking can boost metabolism, which causes your brain to be more active and could lead to nightmares, according to the National Sleep Foundation.

While some people sleep better after eating a light snack, you should stop eating two to three hours before bedtime. If you notice that you have nightmares afterward, try avoiding nighttime snacking or heavier meals before bed.

Some medications can prompt nightmares by interrupting REM sleep.

"If people can identify that their nightmares either started or increased when they had a change in their medication, that's definitely a reason to talk to their doctor" about their medication schedule or alternatives, Martin said.

Progressive muscle relaxation — tensing muscle groups as you inhale and relaxing them as you exhale — has been effective for reducing nightmares.

"Nightmares activate the sympathetic nervous system, the 'fight or flight system,' the body's natural response to imminent danger," said Tal via email.

Write down your worries to get them all out ahead of time, lest they rear their disquieting heads at night. Journaling can be helpful for alleviating nightmares and stress in general, Tal said.

Since our nighttime observations can appear during sleep, "spend some energy engaging with things that are more emotionally neutral or even positive" before bedtime, Martin suggested.

During the pandemic, our everyday lives are looking pretty scary, too. "Reading the news media and then hopping into bed is more likely to trigger disturbing and upsetting dreams than looking through pictures from your last vacation with your family," she added.

Imagery rehearsal therapy is effective "when the chronic nightmares are showing similar themes and patterns," Tal said.

Since nightmares can be learned behavior for the brain, this practice involves writing down in detail the narrative elements of the dream. Then rewrite the dream so that it ends positively. Just before falling asleep, set the intention to re-dream by saying aloud, "If or when I have the beginnings of the same bad dream, I will be able to instead have this much better dream with a positive outcome."

Silence is key in a sleep routine, but "for people who either don't like it to be completely quiet or who are awakened by noises they can't control during the night," background noise "is a good strategy," Martin said.

Try a fan or a white noise machine or app for several consecutive nights to help your brain adapt, she added.

If nothing works and you're still having nightmares, talk with a therapist or sleep specialist.

"Nightmares might be a sign of a larger issue, such as PTSD or a mood disorder," Tal said. "It is possible to treat the nightmares without treating the underlying disorder, but it may also be helpful to treat both the symptom and the disorder.
