Yes, quite. They can be affected by the kind of tunnel vision you get when you're very stressed out. Like remembering a spot on the wallpaper, or a brass part of the handrails on the stairs where my parents gave me some bad news when I was four.

Unfortunately I can't seem to decide what sticks and what doesn't. I don't have perfect recall (far from it). I can barely remember what I had for dinner yesterday, but if I do I can probably still taste it.

Yes, but I think there's something even worse: things that haven't happened.

Anxiety is kicked in to overdrive when you can vividly imagine adverse outcomes to such a degree that they are indistinguishable from things that have happened.
