Mine is convoluted and too subtle to be observable. I like to include dialogue samples of the film I'm working on into the music. Usually warped beyond recognition, so if anyone would notice it would be a blip on the subconscious level. Okay, so some examples of what I'm talking about:

This is the first bit of music in the feature "Fetish Dolls Die Laughing" I did a year ago. The washy sound that starts around 6 seconds in is from later in the movie, where the killer (the possessing spirit of the Tickle Monster...no, still not making this up) says "I Exist". General creepy sound, but in context, foreshadowing the rest of the film (in a subtle, unnoticable way).
For that film, I also did a song for the credits, and used the samples again at the beginning:

And going WAY back to the first film I ever did (when I was doing more ambient/noise, rather than film music):

The noise piece that plays inside the woman's head (the color stuff) constructed ENTIRELY out of her dialogue. She says "I'm fine" but inside is screaming it, etc.
Crazy pretentious, and no one ever, ever notices. But it makes ME happy, and keeps me thinking about sound in the context of the narrative.
