I have, several/many times. Sometimes it's just awkward, sometimes it's more scary because aforementioned SO takes it very badly. I once had to prevent some kind of restaurant (!) fight after I got whistled at.
I did when I was in 5th grade and our reading class had multiple things for use to choose from to do a book report on what we read: Make a board game, make a short comic with four panels, or some other crazy way. I always chose to make a board game out of it because it was easier to do since I nevwr read any of the books for that class. X3
Have you ever dreamt lucidly or realized you were asleep and decided to try and take control?
