I'm Nervous

It's getting to be bed time. I'm scared to sleep in my bed. Sound like a 5-year old? I took a nap this afternoon. When I woke up, I got up and started to make my bed. There was a ginormous spider crawling on the bedskirt. A huge black spider. The bed was pulled out from the wall as I kept track of the spider's movement. I finally got it though! All I keep thinking about is that it was crawling on my bed while I was sleeping. Ewwwwww, my skin is crawling. Crawling. What if it was crawling on me while I was asleep? How can I go to bed?
