Yes!! I really like that last point in your list? It's so easy for us at least to sort of... get caught in loops of "well maybe it isn't them, maybe it's just us, maybe we had a rough week or maybe there was something else that set us off or maybe..."

I don't know if we have proper memory gaps, either - it's really freaking hard to get yours truly fully away from front, even just knocked out, and because of that I don't know if we really lose time in the classical sense? That being said, we definitely have a lot of memory irregularities. It's like we're constantly drifting around in a haze and information doesn't really stick to our brain unless we try really hard. Anything we're thinking about just poofs at random, or like... suddenly gets wiped away, like a windshield wiper, and in order to remember it we have to literally have to rewind our environment and spacial position and hope that it triggers something in our memory. And everything beyond a few hours ago feels unreal; everything beyond a day or so ago is one big confusing blur.

(Apparently this is closer to most experiences of time loss/amnesia than the "classical" blackout, though? I'd honestly love to see more discussion of this.)
