Yes, video games can cause nightmares: dream researchers find that scary or violent games turn up in bad dreams, mostly in children and in people who play them right before bed. The surprise is on the other side. People who play a lot often have milder nightmares, and some of them fight back inside the dream instead of running.
The numbers are smaller than many parents fear. In a survey of 2,546 secondary-school children in Belgium, media researcher Jan Van den Bulck found that computer games were linked to nightmares in about 10% of boys and 5% of girls. Television did more damage: TV content showed up often in the nightmares of 33% of the children.
Games also feed good dreams. In the same study, most 13-year-olds said games had appeared in pleasant dreams too. So the real question isn’t whether games get into your dreams. They do. It’s what kind of game, when, and who’s holding the controller.
Can horror games cause nightmares?
Horror games can cause nightmares, and timing matters more than the game itself. A horror game is built to keep your threat system switched on: the corridor you can’t see the end of, the noise behind you, the low battery. Stop playing at midnight, fall asleep at 12:15, and that alarm is still running when your first dreams start.
A 2016 study published in Dreaming backs this up. Van den Bulck and his colleagues surveyed 1,287 people aged 10 to 60 about their media use, video games included. Those who had taken in violent media within 90 minutes of bedtime were 13 times more likely to have a violent dream that night.
Who’s playing changes the picture. Younger children are still learning where fiction stops, and kids who are anxious by nature, or already stressed by something at school or at home, are the ones most likely to take a game’s monsters to bed. Some adults are the same. Others play horror every night and sleep fine.
Nightmares are a normal part of dreaming, whatever you play. In the Dreamly analysis of 189,480 dreams, fear and nightmares make up 7.2% of an average dream journal. A game can raise that share for a while. It rarely creates the fear from nothing.
Why video games show up in your dreams
Video games show up in dreams because the sleeping brain replays what you’ve practiced hard and recently, and few things are practiced as hard as a game. Hours of attention, the same moves over and over, real wins and real frustration: that’s exactly the kind of material sleep likes to rework.
The best-known proof is the “Tetris effect.” In 2000, Harvard sleep researcher Robert Stickgold had 27 people play Tetris over three days. As ScienceDaily reported, 17 of them saw the same thing as they drifted off: falling Tetris blocks. Three of the five amnesic patients in the study saw them too, despite having no short-term memory. And according to Scientific American, a couple of experienced players saw the Nintendo version they’d played years earlier rather than the one in the lab.
It doesn’t stop at sleep onset. In a 2016 survey of more than 2,000 gamers from 78 countries, Angelica Ortiz de Gortari and Mark Griffiths found that 97% had experienced at least one “game transfer” effect, like hearing a game’s music after turning it off, and 28% had it while falling asleep. Dreams about video games are the night-time version of the same thing.
Dreaming of playing video games
A dream about playing a video game usually means your brain is still processing the game, or the feeling it gave you. If you were playing with friends, the dream is often about the friends more than the game. If you were stuck on a level, failing the same jump again and again, it tends to show up in weeks when something in your waking life won’t move either.
Dreaming you’re inside a video game
Dreaming you’re inside the game, with its world around you instead of on a screen, is common after long sessions. The menus, the health bar, the map in the corner: your brain borrows the game’s rules because they’re fresh. People who play a lot also seem to dream more often from outside their own body, the way a game camera sees a character, as our page on dreaming in third person explains.
Do gamers have fewer nightmares?
Frequent gamers often have milder nightmares, according to research led by psychologist Jayne Gackenbach at MacEwan University in Canada. She calls it the nightmare protection hypothesis: years of facing virtual threats may teach the brain to face dream threats too.
In a 2011 study of soldiers published in the journal Dreaming, Gackenbach’s team found that frequent gamers had less threat and less war content in their military dreams than soldiers who rarely played. When the team repeated the work with students who had lived through a trauma, the picture got more complicated. In that 2013 follow-up, male heavy gamers seemed less troubled by nightmares, while female heavy gamers were the most troubled.
Treat it as a lead, not a rule. The authors themselves narrowed the effect to men who play a lot, play socially and mostly skip casual games. The studies are small, and they show links, not causes. But they fit what gamers describe. Speaking to LiveScience in 2010, Gackenbach summed up their threatening dreams in one line: “They don’t run away, they turn and fight back.” She was careful to call it a hypothesis.
Children, video games and nightmares
Children are the group most likely to get nightmares from video games, because they’re still learning where a story ends and real life begins. Van den Bulck also found that media influence on dreams wasn’t limited to kids who used screens excessively. An ordinary amount of the wrong game, at the wrong hour, is enough.
Most of what helps is simple. Check the age rating (PEGI in Europe, ESRB in North America) before the game, not after the first bad night. Keep at least 30 to 60 minutes of calm between the last session and lights out. Ask what they played and how it felt, without making the game the villain. Our guide to children’s dreams covers the rest of what kids dream about at each age.
If a scene keeps coming back, help your child change its ending while awake. The monster shrinks, a friend shows up, a door appears. Drawing the new version helps younger kids.
What to do if video games give you nightmares
Move the scary game earlier, and end the evening on something calm. That one change handles most game-related nightmares. If you can’t stop mid-story, finish the session on a save point you’re happy with rather than in the middle of a chase.
The same goes for the phone in bed. Our page on doomscrolling and nightmares shows how late-night screens feed bad dreams even without a single zombie.
Then look at the dream itself. Was it the game’s monster, or something from your week dressed up as one? Write down the scene and the feeling as soon as you wake. A private dream journal like Dreamly helps you see whether nightmares cluster after certain games or certain kinds of days, and gives you a reading of your own dream rather than a generic list.
If the same nightmare comes back, rewrite its ending during the day and rehearse it for a few minutes before bed. It’s the basis of imagery rehearsal therapy, explained in our page on recurring nightmares. And if nightmares come most weeks, make you dread going to sleep, or follow a real frightening event, talk to a doctor. For a child, start with the pediatrician.
Can video games cause nightmares in adults?
Yes, but less often than in children. Adults mostly get them after a horror or violent game played late, or after a game that hit a real fear. Adults who play a lot often report milder nightmares, according to Gackenbach’s research.
Is it bad to play horror games before bed?
It raises the odds of a bad dream that night. Violent media within 90 minutes of bedtime was linked to a 13-fold higher chance of a violent dream in Van den Bulck’s 2016 study. If you love horror, play it earlier and wind down with something else.
Why do I dream about video games I played years ago?
Because old games are stored memories like any other, and the brain mixes them into new dreams. In Stickgold’s Tetris study, experienced players saw the older Nintendo version they’d played long before. A familiar game world can also stand for the time of your life when you played it.
Do video games make dreams more vivid?
They can make some dreams feel more like a game. Frequent gamers in Gackenbach’s early studies reported more dreams seen from outside their own body, and often flipped between that view and their own eyes. It’s not a sign of anything wrong. Practice shapes the way you dream.
