I like to drink something sweet before falling asleep. A couple big gulps of cranberry juice gets the dreaming more vivid. Some nights my dreams are never ending. I flow from one into the other. Nothing really gets finished, but there's always more to see.
One thing I do find very annoying is when you wake up right before it's done. A great plot, involved story, just about to reach the dramatic conclusion, when the phone rings in your mind. You wake up & try as you may, but can't get back there.
I, like most people in life, don't know where they're headed. I always hope before I sleep, that I get some sort of direction in life from my dreams. It's usually just a bunch of regurgitated episodes from my memory. Entertaining yes, but I'm not getting anywhere.
