Look at what you've written. It's probably messy, scatterbrained, discursive, amusing. That's fine! Freewriting is supposed to loosen the mind, take away the inhibitions that many writers face when they stare down a blank page. Think of athletes who stretch their muscles before a race. It's the same idea: you're getting yourself used to the act of writing, and letting all the little nuggets stored deep in your mind come out into the light. You may even hit on some fascinating thoughts that you want to write about further. Explore your mind--it's like dreaming when you're awake, and capturing the word and image flow on paper.
