I absolutely love double exposures. I was always too afraid to do them on film. A lot are done "digitally" these days (so much so, after the fact) - and that's upsetting.

I have also experimented with long exposures and strobing the flash multiple times when doing portrait shots, particularly of dancers. While technically not multiple exposures, it achieves a similar effect, and ties two distinct moments together.

But, well; on the topics of moments, and photography, we're just capturing a sliver of light, which is a sliver of time, but to capture them in two places, and to let that light blend on the photographic medium is one of the most awesome things we can do to master that medium.
