I had no idea this was a known phenomenon. I had experienced this for a while some years ago. I tried to tell my doctor about explosions in my head while falling asleep, but she had no idea what it could be after ruling out seizures. Mine were like a really loud explosion with a bright flash of light. It was obvious it all took place in my head, but it always came with this sense that I had been hurt even though there was no physical pain after.
Interesting to know there’s a name for this. Thanks for sharing!
I get it too but only if I’m trying to fall asleep on my back. 3 weeks ago I got a really strong one, I could still feel the shock in my brain for a minute after.
Like this : imagine a sound. For example, a cat meow. Meow meow. You doing that? Are you “hearing” that meow in your “mental sound space”?
Now imagine the sound is 500x louder. And it isn’t a meow, its an explosion.
It sounds like the blast of compressed air when you disconnect a compressor fitting.
That’s what it’s like.
It happens in half-sleep.
I’ve had big blasts that make me go “woah” a couple times a month since forever. I had a really big blast that made me go “holy shit!” just a couple days ago.
I heard something a few days ago that sounded 100% like someone crashing a car through my apartment. I jumped up and looked around, and nothing was happening. Sometimes it just sounds like a gunshot next to my ear, but usually it sounds like an industrial crash. Screeching metal exploding.
Wow! Now I have a cool name to this phenomenon. Doesn’t happen every night and there are also times I can ignore it because it’s typically not scary, just disruptive. I also see the flashes of light and that can be scary sometimes. I’ll think somebody tried to come in while I’m sleeping or that a nuclear bomb just went off. Or that a cosmic ray hit my eyeball.
Now, is there a phenomenon about seeing random faces in my head while falling asleep as well?
I used to have all this as a chronic weed user, if you’re the same maybe try stopping and see if they go away. The only one I still have is the flashing lights, but it’s rarer.
Mine goes ShhhhshhiINNKK!!! Starts kind of static like and within the same second makes a sound like if you flicked a really thin glass really hard, but with a metallic finish. I also see a flash of purple/green/silver color on my eyelids when it happens.
When I was deployed in Afghanistan, everyone I knew had the same reoccurring dream- some other dream is happening, and then out of nowhere, you hear a gunshot/explosion, and wake in a cold sweat, absolutely certain that you just got shot or blown up. And the certainty persists for about five seconds after you wake, as you shakily pat yourself down for blood. Good times.

Unless you also happen to get sleep paralysis at the same time! Happened to a friend who fortunately was in a tent full of very understanding people when he woke us up screaming.
There’s possibly some relation there, but I have hypnic jerks almost every night and EHS every now and then and as far as I’m aware I do not have synesthesia.
Interesting Q lesbian_seagull. I never got the sense that anyone else was involved, but the sound is definitely slamming shut with a loud thwack. And I suppose the first couple times I thought it was real, but I don’t have screen doors.
Wait, is this my “nightmare sound”? When I have nightmares (fairly rarely, but I’ve gone through times when they were more common) there’s a sound that goes with them, and builds in intensity as the fear comes to a crescendo. It’s like a high-pitched whine that starts as a hum (like tinnitus) and slowly grows to ear-splitting intensity, except it’s more like head-splitting because it feels like the origin is in the center of my head. And I say “feels” intentionally because it’s not just a sound, it feels like my consciousness is vibrating apart.
Often the actual content of my nightmares is mostly abstract (like worrying about why the room is dark, or feeling followed but not knowing by what) and the terror is completely disproportionate to the events, but directly proportional to the intensity of the sound.
Uh, for me it’s firmly inside the dream though, I wouldn’t classify it as a hallucination. When I was taking antidepressants I used to have hallucinations wake me up—like waking up because I heard my mom talking, when she was in a different state—but that felt different. That was like hearing someone in the room with you and having it pull you out of whatever dream you were having. The “nightmare sound” is inside the nightmare, it isn’t what wakes me up.
I used to have that when I was a teenager. About one out every ten times I was falling asleep just at the moment I drifted off I’d feel this crazy big pop that went from deep behind my right eye to the top right part of my skull. Sometimes it was more like a noise, sometimes it was more like a physical impact, like somebody bounced a golf ball off of my skull. It was really annoying. It started to happen less and less as I got older though. It pretty much went away completely by the time I was in my late 20s.
I get that as well! When it’s not a horrifyingly loud boom, it’s like an increasingly loud wind sound. When I get that one, it’s accompanied by my body feeling like I’m in a wind vortex being whipped around every direction. Makes me scared to go back to sleep.
