At the outset of Chapter 4, Hannah is disoriented. She has opened the closet door and entered a world that is completely foreign from the Passover dinner. Once the door closes, she can no longer see her family, the dining room, or the world that she once knew. Right now, at this point, she sees herself as "daydreaming." As with all plunges into a world of conditionality, she struggles to find answers. One particular answer that she comes up with is that she is drunk. She drank the wine from the Seder. In Chapter 3, Hannah noted that she experienced a "buzz" from it. The throbbing headache that followed help to establish a condition in which she believes that her "daydream" is a result from the wine. She thinks that she is a bit drunk from the wine and seeing an entire set up that might not exist and might not be real.
Hannah thinks that the explanation of her daydream is in the wine giving her visions. The entire scene is something that Hannah attributes to the wine. Yet, the force of it becomes all too real. When the reality of Hannah being Chaya becomes clear, Hannah realizes that it is not the wine. Rather, she has entered into a portal of time where the reality and meaning of symbols such as Passover are compelling and powerful.
