Sort of counts: I was in the grocery store once, going up and down the aisles looking for some obscure thing, and my "Ctrl-F" fingers kept twitching.
My friend and I played a two-day Halo marathon this past weekend, and whenever I closed my eyes to go to sleep I saw in the upper right of my vision, "Hold RB to swap for" and a picture of the Battle Rifle.
After playing Half-Life 2 all day, I kept trying to turn on a flashlight I didn't have when it got dark in my house.
When I was driving home from work at night, I kept expecting a mini-map to be present on my windshield somewhere. (Cuz I couldn't find the turn-off in the dark)
