Can the creatures in this house just leave me alone?

During the middle of the night, I woke up because I had an itch on my leg. It felt like something was crawling on me. Sometimes I get paranoid and think things are crawling on me, so I just assumed that's what was happening. Anyway, I reached down to scratch it, AND A SPIDER WAS ACTUALLY CRAWLING ON ME! That's the sickest feeling ever. I panicked and turned the light on and saw that I had squished its guts on my leg. It was really gross, but I wiped it off and tried to go back to sleep. At least it wasn't a bat.
