In Wuthering Heights by Emily Bronte, Lockwood experiences two nightmares while he spends the night at Wuthering Heights because of a bad weather. In the first nightmare, when he falls asleep at a very old book, he sees its morning and he is with Joseph walking on the road. Suddenly he realizes that they are going towards a chapel. There, he is accused of a sin and whole of the assembly attacks him. He feels tremendous noises, and he suddenly wakes up from this dream and realizes he was actually disturbed because of a tree branch.
Merely the branch of a fir-tree that touched my lattice as the blast wailed by, and rattled its dry cones against the panes! I listened doubtingly an instant; detected the disturber, then turned and dozed, and dreamt again: if possible, still more disagreeably than before.
He sleeps again restlessly and this time again, he gets into the second nightmare, which is even more awful and frightening. He sees himself trying to get that branch out of the window, but just at that time a cold, creepy hand grabs him and begs him to let it in. Lockwood screams and breaks the nightmare. Both these nightmares are actually very symbolic and this is disclosed later in the novel.
Lockwood screeches that the place is haunted. Heathcliff runs listening to Lockwood and gets very upset. He rudely asks Lockwood to leave the room. He gets near the window and begs Catherine’s ghost to come.
