I dream about movies

Mainly words. Articles I just read. With the words it's mainly searching for the right one. It's not language-specific either, I mean it happens both in English and in Dutch. And as far as I can tell, it has little to do with the amount of sleep I've had either. It's puzzling, is what it is. And a bit scary, because I like to think i've got a good vocabulary in both languages, and this searching for words is scaring me a bit.
