Ah the dreaded cog fog. Totally understand that one. Have quite a few stories about that. I have to laugh at myself, otherwise I'd scare my kitties by screaming.
I found a book in the freezer once, not quite sure how it got there. Don't have kids, and can't really blame it on the cats.

I've tried to put the coffee pot in the fridge with the creamer and the pop in the cupboard with the glasses.
The word mixup is fun. I've said things like "we have cake to drink" and "Glad we're flying the car for our trip, that way we don't need to drive on a plane." Of course it takes the stares and chuckles to realize I said anything strange.
When I lose my train of thought, I call it "my train derailment". My hubby, the computer guy, says I'm "blue screening".
