Was it only a Dream?

From what I know about the ending of the story of “Young Goodman Brown “ the character Goodman Brown woke up from a dream. He had waken up not knowing what was going on and overthinking like if he wasn’t in his own body. On my perspective I think that Goodman Brown wasn’t himself, his mind was controlled by someone else. In the story it talks about figure of a person from the forest that was approaching him, probably the figure was a bad spirit and got to his head and made him believe what it wanted him to know.
