An Expert’s Guide to Keeping Bad Dreams at Bay

Martin added that changes in sleep patterns — including fragmented sleep — can make people sleep less soundly, which means they remember more of their dreams.

“Most of your dreams take place during the ‘rapid eye movement’ or REM sleep stage,” Martin said. “Typically, you’ll need to wake up during or shortly after a dream to remember it.”

You can reduce disturbing dreams by getting a good night’s sleep, so Martin offered some tips.

Have consistent times for going to sleep and waking up. Adults need seven or more hours a night on a regular basis for ideal health.

Limit your exposure to stressful news near bedtime so you’re not dwelling on it as you try to doze off.

For at least 30 minutes before turning off the lights, prepare your body for sleep. Some good ways to unwind include reading, listening to soothing music or meditating.

Limit your consumption of alcohol and caffeine, because both can disrupt sleep quality.

Deal with your worries and stress during the day. For example, writing down your thoughts can help release worries so you’re not dwelling on them when you go to bed.

If disrupted sleep or nightmares persist, speak with a sleep professional, Martin advised.
