This is what my dad said: that we aren't aware of our dreams in real time. That the only memory we have of our dreams is just that, when we remember or recall them when we're awake. So even in a lucid dream, we're not experiencing them in real time. Rather, when we wake up, we only remember the lucid dream.

Does that make sense?

Anyway, I think that's BS. Otherwise how could we have dream control? Or am I missing his point?
