I think those examples, as you mentioned in the first example, the cognitive dissonance part, is the discomfort your brain feels in trying to either ignore, or somehow reconcile you conflicting beliefs or actions. If you're fully aware of the contradiction, and have decided to live with it, there's no dissonance, but if you're somehow still believing two conflicting things that are inconsistent, and haven't quite sorted it out, that's the "dissonance" part. The brain pain that creates.
