While the situation would be a startling one without doubt, I am going to assume that you would have a sufficient degree of self-control to keep your mental balance. This would be the easier as you discovered that your mental vision was as clear as ever, and that your real self, which is back of all your senses, had received no shock or injury. You would naturally wish to know just what had happened, and it would be apt to disturb you somewhat to find that your reasoning powers failed to respond when you called upon them to solve the problem, as naturally they would, since the brain, with which they do their work, would share the inaction of the body. Now, if the world of things had thus vanished, what could remain? In the first place, memory. You would be able to call up the pictures of the past, and live over again in your mind any scene there depicted. But you would not be confined to living in the past. Although unable to see or to hear, you would be able to assume the mental attitude either of looking or listening, and as you sought to penetrate the gloom of your surroundings, you would be conscious of lifting eyelids which perhaps had never been raised before, and the mystic light of another world would dawn upon you. Shadowy forms of graceful outline would be seen, at first dimly, then with greater clearness. You would not mistake them for mortals, and, having no acquaintance with other-world intelligences, you might take them for moving pictures, destitute of any kind of life. Presently you would become aware that connected thoughts were passing through your mind, without conscious volition on your part, and assuming the attitude of a listener you would discover that the inner world of sound was opening to you. The subject treated of might not relate to you personally, but you would hail with delight the opportunity to prove yourself in communication with other minds.
