"Well, it seems a weary number of hours," she muttered doubtfully: "it must be more. I remember being in the parlour after they had quarrelled, and Edgar being cruelly provoking, and me running into this room desperate. As soon as ever I had barred the door, utter blackness overwhelmed me, and I fell on the floor. I couldn't explain to Edgar how certain I felt of having a fit, or going raging mad, if he persisted in teasing me! I had no command of tongue, or brain, and he did not guess my agony, perhaps: it barely left me sense to try to escape from him and his voice. Before I recovered sufficiently to see and hear, it began to be dawn, and, Nelly, I'll tell you what I thought, and what has kept recurring and recurring till I feared for my reason. I thought as I lay there, with my head against that table leg, and my eyes dimly discerning the grey square of the window, that I was enclosed in the oak-panelled bed at home; and my heart ached with some great grief which, just waking, I could not recollect. I pondered, and worried myself to discover what it could be, and, most strangely, the whole last seven years of my life grew a blank! I did not recall that they had been at all. I was a child; my father was just buried, and my misery arose from the separation that Hindley had ordered between me and Heathcliff.
