DCs are mostly irritating when I have lucids but sure they vary. In one lucid I announced that I was lucid and started increasing vividness and one of the DCs I was with was just mocking me the whole time at which point I commanded a less annoying DC to behead him.
I think it's related to my view of people in waking life. Generally I'm quite antisocial and can't stand to be bothered which causes me social anxiety. This likely creates a negative expectation which is met by negative events in dreams. Also, people I find more irritating in waking life are more likely to attempt to hinder me in a dream.
