I could cite you more than one hundred incidents corroborating the truth, that people have a very confused idea when their senses are tied up by fear and anxiety. As soon as cool reflection gives way to the horrors of a disordered fancy, we are but too apt to create phantoms and spectres all around us, we do not see what really exists, but what we fear to behold.
