We've all done it... Doing something with our character and imitating it in real life, even simultaneously. I've had wine and cheese at the same time as I've had my character eat food (yes, I swallowed at the exact same time as I pressed "eat") and I've taken up archery. The latter I haven't been able to perform at the same time as I play, but the inspiration came from the game.
... I'm mentally stable, I swear.

Ever matched what you do in real life with what happens in the game.
Not Really, I once created a character that somewhat resembled me. Could not get it just right do to the limitations, but it was close.

If I matched what I do in the real world to what I do in the game, it would be a very boring game. RFLOL

I sometimes break into people's houses and murder them if they catch me but that's about it.

I have often stared at the idiot in front of me in line at the store taking forever to purchase a pack of gum. Let's just say it's good that I did not handle those situations the same way I would have in the game.

This is great.
I have gone looking for food I've seen in the game like fresh bread and cheese, but I don't make my character eat it. Would be cool if games got more people interested in things like archery. I am a fencer, rider and archer, and currently use a custom made long bow, but the real stuff came before the games with me. Sadly I've seen our archery club struggle, and the fencing group I started with an Olympic medal winning fencing master only lasted a year before it closed down due to lack of interest. If everyone who enjoyed waving a sword around in Skyrim took up fencing lessons that would be pretty cool.

I tend to make my character eat when I feel hungry and sleep when I feel tired. Although I don't do those things at the same time - except for a very embarrassing experience where I came home tired and started playing Skyrim to wind down and fell asleep at my keyboard when I made my character sleep.
