....Well....
When you hear a clicking noise, glance down, swear you see a giant fucking centipede crawling on the underside of your laptop, and immediately proceed to flail in a mad rush to get the fuck away only to realize a second later that the clicking noise was a fan, and there is no centipede and you've just worked yourself into a full-on panic of heart racing, and oh god so many legs kill it kill it kill it for absolutely no reason, it's probably time to go to bed...
