I think the only thing persistent in my dreams is the way I make decisions, as in my "logic" is the same one I would use in real life if under the effects of the emotions in the dream. It's a bit warped since it's applied to situations that would never happen, but how I generally act in real life is how I act in my dreams, sometimes infuriatingly so.

This only goes for the way I make decisions though, I don't think any of my daily habits are in my dreams.
