You are correct! Scrooge sees he has to go along with these super natural entities. He is afraid, but he recognizes that they aren't there to hurt him, so he wants to get things over with.
""Spriti," said Scrooge submissively, "conduct me where you will. I went forth last night on compulsion, and I learnt a lesson which is working now. To-night, if you have aught to teach me, let me profit by it.""
— Dickens, pg.48
A part of Scrooge also sees that he needs to change.
