the "less dramatic version" you're describing is just... what DID is like for the overwhelming majority of people who have it. you're not having a different version of DID, you're having regular ass DID. it's a covert disorder - the parts don't just hide from you, they work together to stay hidden from other people too. as Howell puts it (describing the dissociative psyche), the parts "operate in concert to keep themselves hidden from other people. All of the emotional action takes place internally." the disorder primarily affects the perspective through which you understand the world, and that's what shapes how you interact with the world, other people, and even yourself. it's an inside job, not a stage show.

it's also worth knowing that fragmentation exists on a spectrum even within DID. Fisher describes how in any given person it can be "more subtle and permeable or more dramatic and rigid" all within the same person. and DID systems specifically tend to have a well-developed "going on with normal life" self, often with parts for work, parenting, socializing. this means the disorder is structured around maintaining an appearance of normal functioning. looking functional isn't evidence against DID. it's part of how it's architected. (is that a word?)

something incredibly important to remember: the thing people with DID that you see online have in common isn't just DID. it's posting about personal things online, which is its own personality trait that filters what makes it to the outside world. nobody's posting "dear online people. today i did not know what was going on. i might have been an alter but might not have been. nothing really happened and i didn't act all that different" (or if they are, those posts aren't the ones that are very popular.) you're comparing your possibly dimly lit interior to other people's highlight reels.

the TLDR is that you might be less consistently florid than what you see on apps onlines but most people with DID aren't consistently florid either. Kluft found most only have small "windows of diagnosability," brief periods where the disorder is overtly observable at all. the rest of the time it looks like... a person, having a day. that's not a lesser version. that's just how the disorder is.

tldr tldr: what you're describing is normal. it makes complete sense and its not "being different people" disorder. it's a disorder where your ability to interact with the world as one consistent self is diminished. there's nothing in the criteria requiring for you to be dramatic.
