I had a thousand different surmises about the meaning of this odd incident; and could not conceive how any human creatures should be in my kingdom (as I called it) but myself, and I never yet see them, or any trace of their habitation. But then again I reflected, that though I had surrounded the whole lake, yet I had not traced the out-bounds of the wood next the rock, where there might be innumerable grottoes like mine; nay, perhaps some as spacious as that I had sailed through to the lake; and that though I had not perceived it, yet this beautiful spot might be very well peopled. But, says I again, if there be any such beings as I am fancying here, surely they don't skulk in their dens, like savage beasts, by daylight, and only patrole for prey by night; if so, I shall probably become a delicious morsel for them ere long, if they meet with me. This kept me still more within doors than before, and I hardly ever stirred out but for water or firing. At length, hearing no more voices, nor seeing any one, I began to be more composed in my mind, and at last grew persuaded it was all a mere delusion, and only a fancy of mine, without any real foundation; and sometimes, though I was sure I was fully awake when I heard them, I persuaded myself I had rose in my sleep, upon a dream of voices, and recollected with myself the various stories I had heard when a boy of walking in one's sleep, and the surprising effects of it; so the whole notion was now blown over. I had not enjoyed my tranquillity above a week, before my fears were roused afresh, hearing the same sound of voices twice the same night, but not many minutes at a time. What gave me most pain was that they were at such a distance, as I judged by the languor of the sound, that if I had opened my door I could not have seen the utterers through the trees, and I was resolved not to venture out; but then I determined, if they should come again anything near my grotto, to open the door, see who they were, and stand upon my defence, whatever came of it: For, says I, my entrance is so narrow and high that more than one cannot come at a time; and I can with ease despatch twenty of them before they can secure me, if they should be savages; but if they prove sensible human creatures, it will be a great benefit to me to join myself to their society. Thus had I formed my scheme, but I heard no more of them for a great while; so that at length beginning to grow ashamed of my fears, I became tranquil again.
