I know that I'm part of reality. I know that I've been living a life and affecting things for - as of today - twenty-one and a half years. However, when I experience derealisation, there's a part of my mind that doesn't.
I thought I had written the story in a very mature way. But, when I was editing and rewriting it over the next few years, I could definitely tell that it had been written by somebody who did not fully understand the topic they were writing about.
