In the story "The Third Level", by Jack Finney, what does the narrator mean by "–maybe that's how the tunnel I got into..."
Is it a typo? On the other hand, I can't seem to find the correct version online. This is what I got from my textbook online.
Context
I turned into Grand Central from Vanderbilt Avenue, and went down the steps to the first level, where you take trains like the Twentieth Century. Then I walked down another flight to the second level, where the suburban trains leave from, ducked into an arched doorway heading for the subway — and got lost. That’s easy to do. I’ve been in and out of Grand Central hundreds of times, but I’m always bumping into new doorways and stairs and corridors. Once I got into a tunnel about a mile long and came out in the lobby of the Roosevelt Hotel. Another time I came up in an office building on Forty-sixth Street, three blocks away.
Sometimes I think Grand Central is growing like a tree, pushing out new corridors and staircases like roots.There’s probably a long tunnel that nobody knows about feeling its way under the city right now, on its way to Times Square, and maybe another to Central Park. And maybe — because for so many people through the years Grand Central has been an exit, a way of escape — maybe that’s how the tunnel I got into... But I never told my psychiatrist friend about that idea.
Both paragraphs are together and not separate. And while the phrase is in the second paragraph, I added the first one for more context
