We know pretty well what matter is and how it interacts with the others.

Dark matter interacts through gravity but not light. Beyond that I haven't heard much else.

And lastly anti-matter has an opposite charge and interacts with matter through annihilation. I think I remember hearing that it would react with dark matter the same way.

So my question is, does anti-dark matter exist, and what are it's properties?

Speaking of our incomplete theory of gravity, do gravitational waves behave similarly to ocean waves in that they can combine together to create a bigger wave? And if so could there be rogue gravitational waves like there are rogue waves in the ocean?

Yes, gravitational waves follow the superposition principle and can combine to create larger amplitudes, but they don't form true "rogue waves" like oceans since theres no equivalent to the nonlinear interactions that cause ocean rogue waves.
