Other than the fact that the event as I described it could not fit with a materialistic worldview, you have no reason whatsoever to think I am "delusional". And, if you accept that I am not delusional, then your "ANIMAL" or "PEOPLE" explanation does not explain all of the events. Perhaps you'd like to try to reconcile the events that occurred (again assuming that you agree that I am not delusional, at least for the sake of argument) with either an animal or a person making the walking sounds. I sit with rapt attention, awaiting your revelation.
