Give an account of Lockwood's second dream.

Lockwood wakes up, hears that a sound in his dream had really been a branch rubbing against the window, and falls asleep again. This time he dreams that he wanted to open the window to get rid of the branch, but when he did, a "little, ice-cold hand" (25) grabbed his arm, and a voice sobbed "let me in." He asked who it was, and was answered: "Catherine Linton. I'm come home, I'd lost my way on the moor." He saw a child's face and, afraid, drew the child's wrist back and forth on the broken glass of the window so that blood soaked the sheets. Finally he gets free, and insists that he won't let the creature in, even if it has been lost for twenty years, as it claims. He wakes up screaming.
