Kohberger talked about Visual Snow and Demons in 2011


“I have these thoughts all in my head, I search for someone to relate to me, everyone looks down upon me, no one can relate. As I try to read, suddenly my eyes look right through the words, when I look up, I see blue dots near the center of my vision. When I feel slightly calm, it gets hard to breath, and I see bright dots in my vision. Nothing I do is enjoyable. I am blank, I have no opinion, I have no emotion, I have nothing. Can you relate?”

It can’t be confirmed if these were really posted by Kohberger. And it is uncertain when he was supposedly using heroin. But from all accounts this was a very confused and unhappy teenager.
