It also may be just in your nature to respond badly to arrogance. Everything in your dream is just an extension of yourself, if you don't like other people acting that way, and you're not the type to be that way, then your unconscious may be fighting back.

You could also be unconsciously intimidated by the dream world, and have come to the conclusion that it has more power than it does. If you believe it, then it does.

I don't think the time you LD would have anything to do with how the dream turns out (in that regard), but this is just conjecture. I'm by no means an expert.
