Awkward Morning After (but not really) series concept:
True soul mates, when both asleep, are able to merge into a joint dream so that they may spend not just every waking moment with one another, but their non-waking moments too, if they so please. When true soul mates are unable to realize the true source of their connection this ability takes on a mind of its own... queue unexpected, but not necessarily unwanted, joint sex dreams. If only everyone knew about Joint Dreaming some serious confusion could be avoided.
