There's a version of the hyperphantasia conversation that goes: "Oh wow, so you can visualise things really vividly? That must be so useful for creativity!" And yeah, in some ways, sure. But what this framing misses - pretty significantly - is that the vividness doesn't ask permission. It doesn't check whether you're in a good headspace before deciding to replay something. It doesn't have an off switch.
My partner has aphantasia. When they're trying to sleep, their mind apparently just… quiets down. I asked them to describe what that's like and they seemed confused that I was even asking, in the same way I'd be confused if someone asked me to describe what breathing feels like. It's just what happens. The brain goes quiet. Sleep follows.
I have genuinely lost count of the number of times I've been lying in the dark watching a mental reconstruction of a mildly awkward conversation from three weeks ago, in a level of detail that serves absolutely no purpose whatsoever.
What "intrusive" actually means
The word intrusive is doing a lot of work here and I want to be specific about it - because it doesn't mean I'm choosing to think about difficult things. It means that difficult things show up, fully formed and uninvited, in a way that feels more like being shown something than like remembering it.
Watched a horror film? Congratulations, those images are now part of the visual library and will be retrievable indefinitely. Read something upsetting in the news? The brain will illustrate it. Overheard someone describe something disturbing? Here's a fully rendered version of that, apparently.
My partner can watch the news and process it entirely as information. They understand it, they feel appropriately about it, and then they don't see it. I used to think this meant they were somehow less affected by things. I now think it means they have a form of natural psychological buffer that I completely lack.
The 2am situation
Going to sleep requires the imagery to slow down, and it… doesn't, especially, do that on its own. It tends to keep producing content - memories, hypothetical scenarios, elaborate environments I've definitely never been to - until it eventually tips over into actual dreaming, which is its own entirely separate high-definition production.
Things that help, for what it's worth: keeping the room properly dark, doing something genuinely boring before bed rather than anything remotely stimulating, and putting something audio in the foreground so my attention has somewhere specific to land. Podcasts about fairly mundane topics work well. Anything narrative or too interesting is counterproductive - I'll just start generating imagery to go with it.
The part where I admit it's also kind of brilliant
All of this is real and I'm not exaggerating it for effect. And yet - honestly? I don't think I'd swap it. The same system that produces unwanted 2am reconstructions is also the reason music feels almost physically immersive, the reason I lose hours in books, the reason creative work feels like discovery rather than effort. The costs are genuine. So are the things that come with it. I'm still figuring out the ratio, if I'm being honest.
Where do you land?
If this resonated - or confused you - the free test will tell you exactly where you sit on the spectrum.
