I do this too, though I have one scenario that I replay variations of where a disgruntled employee comes back with a group of mercenaries to take revenge and "do damage to the company" and I take them down John McClane style.

I of course am handsomely rewarded by the company and both respected and a little feared by my coworkers. That's usually where I snap out of it since that's the most unbelievable part.
