history: There was this giant spider in my room. I'm afraid of spiders. I went to get something to get it with, and I came back. The spider is now missing. Oh great. There was a big spider in my room_comma_ so I went to get something to scoop him up with (or flatten_comma_ I hadn't decided between the two yet). I come back and he's disappeared. 
current: oh oh, so now you don't know where your enemy is hiding.  Sounds scary.
next: It's scary and annoying because now I have to systematically check every inch of my room because I'm definitely not sleeping here with that big ol spider somewhere in my room!
