Trigger warning

I just thought more deeply about it, and now I know why I have the visions of hanging...

When I was 19, I had my first major episode, and was hospitalized because of psychosis. While I was in the hospital, I was entertaining myself during the day, and saw a bunch of medical personnel rushing to my room. It turns out my roommate somehow got a hold of an electrical cord and hung himself... He was successful. I never saw him hanging, but that would explain why have these visions.
