I occasionally (not frequently) get fragmentation, although I think I had more of it when I was younger. Now it seems to happen more with photographs, and not consistently.
I do the mono channel thing. When I'm in conversations I can remember what was discussed and said but I sometimes can't remember what I saw during the conversation.
I can still be shut down by sensory overload, and have been multiple times in the past month.
This was a major reason I started investigating whether I am autistic again.
I am often sensitive to light (photophobic) to the point of actually wearing sunglasses in my own bedroom. I always wear them outside and anywhere lit by fluorescent lights.
I can't filter sounds very well, but I can filter vision.
I get delayed processing a lot, including the whole respond immediately on autopilot.
I was diagnosed as nearsighted in the first grade, but I stopped wearing glasses by the third grade. I am not sure what happened there, and I've had fairly acute vision both near and far for my entire life since.
Sometimes when someone is talking near me, all I hear is gibberish.
Sometimes I zone out on the sound of someone's voice and don't hear words at all. They don't sound like gibberish, just pure sound.
