But I Cannot Forget That, At Other Times I Have Been Deceived In Sleep By Similar Illusions; And, Attentively Considering Those Cases, I Perceive So Clearly That There Exist No Certain Marks By Which The State Of Waking Can Ever Be Distinguished From Sleep, That I Feel Greatly Astonished; And In Amazement I Almost Persuade Myself That I Am Now Dreaming.
