This has happened to me in the past as well. Thing is, although no one will believe me when I say this (no one ever does) but me and my boyfriend don't argue. We live together and have been together for 2 and a half years so we'e not still in the honeymoon stage :) But I've had dreams like those, where he's done horrible things (but most of the time they're little things but seem really bad in the dream) and I've woken up in the middle of the night and shoved him in his sleep as I was so annoyed. :) Mad huh? I wouldn't worry about it - your subconsious mind is a weird thing and things surface that you didn't even know you could think of - just be glad your boyfriend isn't being horrible when you're awake. :)
