What? No Firefly reference? It's not a good example but I'm sure it counts, I can't remember if it's in Firefly or Serenity, but at one point River wakes up for a fraction of a second and then wakes up again. It's not a long dream in a dream but it's still one (At least Joss says it is)

Technically this phenomenon is called False Awakenings (not suggesting a name change just saying), a true dream within a dream is when you're dreaming, you go to bed in your dream and have some type of second layer dream (usually VERY abstract and surreal) and when you wake up from that, you're back to the regular dream world. You don't realize it until after you wake up for real.

From the number of times I've experienced this, I don't think it's so much nested dreams as it is a fake "awakening" that the dream uses as an excuse for a scene change. There's only ever one "layer;" it just pretends to pop off a stack.
