First, angel is a noun, not an adjective. Angelic is the adjective. Second, it is possible to think of things that one has not observed, for example, a person in a rage envisioning harming an enemy, or a person under the influence of drugs having hallucinations, or a person undergoing considerable stress or strain envisioning things that did not ever enter their field of vision, or observation, prior to having the imagined visions. Further, it is a matter of course for novelists to create entire communities that they never observed, but that were products of their imagination. Regards, John Companiotte, Atlanta, GA USA
