OK, I'll go first. I'd correct people's grammar and spelling a lot, and I'd tell overweight people how to lose weight.
Oh wait, I misunderstood the afterimage thing. No, I usually don't see them while I'm looking at something, only when I close my eyes or look away. I do sometimes get the effect you describe, but not often. I tried to see the 'snow' again just now, but I didn't see any.
I definitely see afterimages, and I thought everyone did. I get movement in textured surfaces, but it doesn't look like 'breathing' at all. I get visual snow, but *not* with my eyes closed, only when I'm trying to see if it's raining outside, which can be hard to tell sometimes.
I made a midi file of it, because I wanted to hear what it sounded like. Let's see if I can share it.
Allen Carr's Easy Way to Stop Smoking and Allen Carr's Easy Way to Control Alcohol have helped me stop smoking (20+ years ago) and drinking (2+ years ago). Can't recommend those enough!

Grocery line: I'd think about why I am waiting in it, wishing the supermarket had a self-checkout system like my usual one, which is so much faster and more convenient.
Youtube: background music for work, like music from World of Warcraft, 'world music', classical music.
Experience: compared to most people, I'm probably hyper-conscious of dogs. I like dogs, but only if they're friendly and well-behaved, and until I'm sure a dog is in that category I'm very wary of it (and even if I know a dog is friendly, I still don't want to startle it).
