Why You Fantasize About Weird Stuff During Sex

You’re having sex. It’s good. You’re into it. And then—suddenly—you’re imagining your high school chemistry teacher, a vampire orgy, or being trapped in an elevator with two people you’ve never met. You didn’t plan it. You didn’t even want it. But there it is: your brain’s very own rogue cinema reel.
If this sounds familiar, well: you’re part of the vast, quiet majority of people who’ve had “intrusive” or “weird” fantasies mid-sex.
Why It Happens
The Brain Likes Novelty
Sex is about stimulation—physical and mental. Your brain is constantly scanning for novelty, and fantasy is an easy way to add extra fuel to the fire. Even if what pops up is completely random, it might keep arousal ticking.
Associative Thinking
Your brain makes strange connections under high emotional intensity. That one person you barely remember? The weird film scene you saw years ago? Stored in the mental archives—ready to resurface when you least expect it.
Stress Relief & Control
Sometimes weird fantasies aren’t about attraction at all—they’re about shifting your mental state. Your brain might choose something absurd or unrelated just to help you stay in the moment or escape anxiety.
When ‘Weird’ Is Actually Hot
Plenty of people deliberately bring unusual scenarios into their erotic imagination: alien abductions, food play, dystopian futures, you name it. The “weirdness” can create distance from real life, making it feel safer to explore taboo or extreme ideas without real-world consequences.
When It’s Not About Desire at All
Here’s the thing: fantasising about something doesn’t mean you want it to happen in real life. Psychology calls this “ego-dystonic” fantasy—it’s not aligned with your actual values or desires. The brain can be an unhinged little storyteller that throws up random images purely because the setting (sex) is a heightened state of arousal.
What To Do With Your Weird Fantasies
Notice Without Judging – The more shame you pile on, the more power the thought can have.
File It Under ‘Brain Noise’ – Not everything that shows up in your imagination needs decoding.
Share (If You Want) – If you have a partner you trust, talking about your strangest fantasies can lead to surprising intimacy—and sometimes, hilariously awkward laughter.
Play With It – If it’s safe and consensual, maybe lean in. That medieval dungeon fantasy? There’s a club for that.
Your brain is a chaotic archivist. Sometimes it hands you a beautiful erotic short story; sometimes it throws a leftover scene from a bad romcom into the middle of your orgasm. Neither means anything bad about you.
Weird fantasies during sex are like dreams: often nonsensical, sometimes hot, occasionally disturbing—but always human.
