Welcome to the forums. Don't worry--we're all a little detached from reality.
I'm relatively new to this forum and not positive if anyone has mentioned apeirophobia yet, in this or any other thread. I don't think it's a symptom of reading the book but it definitely coincided with when I read it. It's the fear of the concept of infinity. At first the night sky would just aggravate me and I couldn't look at it directly. As it got more serious I did research and thought it was a weird form of agoraphobia or astrophobia, but after narrowing it down, I realized that it wasn't the stars that bothered me but the potential of infinite emptiness terrifies me. I guess it makes me feel like Earth and people are infinitely insignificant. It's pretty irrational and has been going on for more years than I care to admit. Like I said, I think it's been part of me since before I read HoL but I was so drawn in by the 's potential. It was the first thing I had ever seen that I could relate my stupid obscure fear to.
I had a pretty bad nightmare a few nights ago, its unrelated to HOL but it was scary nonetheless. My brother and I were locked behind a gate inside a colosseum. We were in a very small space about 2 feet across and 4 feet tall so we had to crouch. He was in front of me and for some reason, the space he was standing on was elevated about 6 inches above where I was standing. I suddenly get this horrible sensation like something small is burrowing into the top of my head. I look up and see a ton of earwigs clinging onto the ceiling inches above my head. They all start giving birth to smaller earwigs and the smaller ones fall onto me and start burrowing into my skull. I start to scream and scratch at my head as more of them start to fall on me. While all of this is happening my brother is just sitting there crouched in front of me like nothing is happening.
