What do roaches look like?

I just walked into my bedroom and pulled a shirt out of my clothes basket which was sitting near a window on the second floor of my home and what looked like a black bug crawled out, then flew around and ended up clear across the room. I've been told that roaches do not fly but read that some will, but not often and not far distances. So, is this a roach? Never had a roach problem and I'M PETRIFIED of insects!!
