speaking of dreaming

what do you think about using dreams? Do you use them in your writing? What about when you read about dreams in books other people have written? Like them? Hate them?

And what do you think dreams are? A mish-mash of memory, hope, and fear? Or synapses misfiring.

I forget where I read it but there was an article about dreams that basically said something to that effect. And I might have gone along with the idea if my dreams weren't so specific, so appropriate, and ultimately, revealing.

Tell me what you think about dreams, and writing.
