For me, it happens especially with activities I do over and over again. Washing my hair, while rinsing I will forget if it’s shampoo or conditioner I am rinsing out, have to try to deduce it. Morning stretches I have to do in the same order, because I can remember the order to recognize where I am and do the next thing, but I have no memory of what I just did.

Keeping track of one-time sequences is also a problem, but at least in that circumstance I am more likely to have written material I am referring to anyway.
