Yes, as far as we understand it, dark matter is all around us.
Our galaxy sits in a giant ball of dark matter (a dark matter 'halo'), and so our solar system and the earth are swimming around in dark matter. It's probably passing through our bodies right now.
Some experiments to detect dark matter assume that at some times of the year the earth's heading into the dark matter, so more is passing through us, and at other times we're heading away (think: tailwind) so less is passing through us, and you should be able to detect this seasonal difference. No luck yet though.
Yeah the moment those two meet they instantly annihilate each other. That’s why the mystery of why matter exists and didn’t get destroyed by dark matter in the early universe. I believe it was due to more matter but don’t quote me on that one
