Nightmares & Bad Dreams

We'll explore why bad dreams happen and share a simple bedtime habit that can change them.

What a nightmare is

Nightmares arise during REM sleep, which stretches longer toward morning. That’s why most vivid bad dreams hit after three in the morning and stick in your memory when you wake straight out of them.

When they hit

Most vivid bad dreams show up in the second half of the night, often around three in the morning, because that’s when REM stretches longest.

Common triggers

Everyday pressures like work deadlines, a fever, missing sleep, a nightcap, a big late-night meal, or a scary show can all push the dreaming brain to rehearse threats, turning them into nightmares.

Night-time tricks

If a nightmare wakes you, sit up for a couple of minutes, sip water, look out the window, turn onto your side, breathe slowly, and hold off on telling the story until morning.

Imagery rehearsal

Imagery rehearsal rewrites the nightmare script while you’re awake. Choose a recurring dream you can tolerate, jot it down, change the scary part into a safe or even funny ending, then visualize that new version for five to ten minutes each day.

How long to practice

Research shows just ten minutes a day for two to three weeks can reshape the nightmare script, making the fear fade and sleep smoother.

The one habit to try

The single most useful habit is daily imagery rehearsal, spending a few minutes each evening rewriting the scary ending. It’s simple, paper-and-pen, and can turn a recurring nightmare into a harmless story.
