I don't know much about Dark Matter, but you seem to have it completely backwards. Dark Matter doesn't interact with regular matter; there are no "invisible planets" or "invisible galaxies". According to Wikipedia, the "vast majority of the dark matter in the universe is believed to be nonbaryonic, which means that it contains no atoms". Dark Matter is mainly made up of neutrinos, particles that move through us on a daily basis anyway.
If you want to make a speculative assertion, that's where I'd start, but I wouldn't say I was "convinced" of it. We know so little about Dark Matter, it might not even exist. How anyone can make the leap as to say "I am convinced that it is related to the spiritual world" is beyond me.
