I used to think I was disconnected from reality until I realized there is no such thing. In a way, every brain IS it's own universe, everyone perceives things differently, everyone is the center of their own little universe, everyone is at the same time their own reality and their own nothingness. We were all just thrown here, brought out of an infinite darkness and into the light, and the only certainty here is that we will someday return to the same abyss that birthed us. It's fascinating, really, that there isn't a single person on earth who asked for their own life, and nobody knows why they are on earth. I used to be scared of these realizations, but now I just embrace them, take comfort in them, instead of driving myself crazy trying to figure out why things are the way they are. I gave up but in a good way. I finally let go. It doesn't bother me anymore.
