I hate spiders with a burning passion... so there's nothing more sweet than being able to stab them to death numerous times on a game.
I'm just going to have to keep my feet off the floor every time I'm fighting one, 'cause I'll think "What if one's crawling up my leg right now...?"
Yes, Arachnophobia is a great survival technique IRL, since some spiders are poisonous, but there's no reason to fear them in a game and you can help disconnect yourself from a fear of seeing spiders by forcing yourself to experience it.
I've found that after enough games with giant spiders I simply feel uncomfortable when fighting them in-game, and can tolerate them more IRL. Everybody win!

Except if they crawl slowly and can go on walls/ceilings and then jump out/down at/on you when you least expect it. Then I'm having 10,000 followers.
