Frank always had dreams about the strangest of creatures. They were bug like in appearance and sailed through the cosmos in oval shaped ships and talked in very high pitched voices.
It wasn’t until years later when they invaded the Earth that Frank realized the dreams had never been dreams at all. The creatures had really been trying to communicate with him and to learn about humankind in order to better prepare their invading armies.
Unfortunately they never bothered to ask Frank how big he was. The invasion failed miserably as the strange creatures were only about 3 inches tall.
