I f*cking hate spiders. They are my all-time worst fear. I can't explain it. I remember once when I was like 16 or something I was playing video games (TurboGrafx too, if I remember right) at my dad's old house without a shirt on (it was the middle of summer, no AC). I took a bathroom break and I felt a tickle on my back. Since I was in the bathroom, I half-turned in the mirror so I could see my back and there was this huge furry black spider on my back like 1.5-2" in diameter slowly crawling up me. It was a f*cking mini tarantula. I have had arachniphobia my whole life so this wasn't like the catalyst or anything. But I freaked the f*ck out. You would have thought I got hit with 12,000 volts of electricity at that moment. That was the single scariest moment of my entire life.
EDIT: It's images like these that just reinforce my fear.
