Too busy to write, but not too busy to dream

I've been working and running around quite a bit, so I haven't had time to sit down and write very much.  The dreams continue though.  Some are the full on stories that I'm used to seeing, but others have been snippets and fragments of thoughts.  Instead of new or only vaguely familiar places and people, these shorter dreams seem to be composed of a jumble of images and ideas that I can very easily trace back to their origins in the waking world.  Is there really a difference, or is it all just the same mental mush that's churned up during the night?

Fragments:

I was speaking to a parent of two young boys.  The parent insisted that since he didn't let his kids eat any sugar, there was no need for them to brush their teeth.  I tried to explain that there was sugar in natural food too, and that they should brush their teeth regardless.

I was watching Ghostbusters from the inside, a sort of disembodied point of view that floated along beside the characters.  This time though, when Venkman entered Dana's appartment in search of ghosts, he found them.  A disembodied hand played the piano while spectres flew back and forth through the walls and Venkman and Dana cowered in the corner.

I was a deposed prince or something, running through the forest away from men on horseback with a man obsessed with birds.  We found a cave where someone had kept a stash of random objects.  Among them was a Silby's Bird Guide, which my friend dove for immediately and clutched to his chest in relief.
