Yup.
I have ADHD sensory schtuff (part of my brain is noticing sensory input at all times. I every so often write up a list of everything I'm aware of at any given time. Without thinking about it, the list is at about 50-75. If I start focusing on sensory stuff, that list doubles or triples).
Which is where the PTSD stuff chimes in, as well. When I'm Hypervigilent? Christ. It's the full list. I'm pretty used to ignoring the 50-75 random bits of information. I'm still aware of it, but it doesn't overwhelm me. It's more of like being in a crowded room with everyone talking. You can hear each and every conversation, but you don't have to actually listen to them. Much less be trying to respond. Once the hypervig chimes in though, I actually have to listen. And respond. Envision a crowded classroom of kids all piling on and shouting your name and talking at/to you, while on the phone, with your boss dropping by also trying to talk. Nothing can be ignored. But it's also not just one sense, ever, but all of them.
It's a big part of why I isolate, or conversely go for seeking oblivion (sensory overload, or drugs that drown the world out). I need a break from over active senses.
If I can actually use my senses (sports/movement, crisis of various kinds, etc.) that's another relief outlet. Then things order up by priority. If I'm just sitting around, however, everything has the same level of importance and I drown.
I wonder sometimes if PTSD kicks people's brains into a similar state that ADHD & SPD people are born with (in this area, only, not saying it makes people comorbid). ADHD tricks certainly seem to help, not just me, but my PTSD friends who are in no way ADHD whatsoever. PTSD exacerbates my preexisting stuff, but I've also had a few decades longer of dealing with it
