What is the narrator's attitude towards Catherine Linton? How do we know this?

Do you have a specific chapter reference for this. I know he has a crazy nightmare of Catherine as a ghost at the beginning of the story.

it is a reading comprehension and is about Mr Lockwood visiting wuthering heights but was prevented from leaving to go home because of heavy snow a servant takes pity on him and shows him upstairs where he finds and unused room where he spends the night he then goes on to have a dream about catherine that is all i have. Could you please help me with the questions i have ask? Many thanks.
