Yes, I have dreams of that nature from time to time, leaving me wondering if I'd done some work, or talked with a family member, or even what you mentioned--whether or not I'd gone to the market and picked up some food. They're really bizarre and take a longer time to shake off than more surreal, obvious dreams once I'm awake. I can't say I don't enjoy them, however, due to their vivid qualities and real-life representations. The one thing about them I find irksome is not being able to locate that work I'd thought I'd done, or the food in the fridge or cupboard. The worst was when I was in school and I'd dream I'd done a pile of assignments, only to wake up and find them all still sitting there, waiting for me and incomplete. Then I'd usually be late for class as well.
