That feel when..
... when you wake up in the middle of the night just to find a huge freaking spider crawling on your floor and you're like "meh, im not afraid of spiders", look away for a sec, then look at the same spot again just to realise that you've lost sight of the spider and now cant go back to sleep cuz you're too paranoid and freaked out, + it's hard to sleep in the heat that was generated from you trying to burn the room down after loosing track of the spider.
