There's a reason people warn against wake-up beginnings, whether there's a dream involved or not. Typically, when we wake up, the conflict has yet to begin.
So, it depends. If your character wakes up, has cereal, goes outside, talks to the neighbors...that's not an advisable beginning. But if your character wakes up half-drunk, in a dark room at a party, and he doesn't see his wife anywhere...there's conflict.
Even in that case, though, you might focus on him noticing his wife is missing, rather than the actual act of waking up. It's easy enough to mention in the second or third sentence that he had just woken up.
I'm sure editors and agents see a lot of dull wake-up beginnings, but they wouldn't necessarily shy away from a wake-up beginning that involves heavy conflict. In fact, better advice is to ALWAYS begin with conflict of some kind. Do that, and cliches don't matter.
