How does the author use foreshadowing in The Pit and the Pendulum?

Example of Foreshadowing:

"here came thronging upon my recollection a thousand vague rumors of the horrors of Toledo. Of the dungeons there had been strange things narrated—fables I had always deemed them—...Was I left to perish of starvation in this subterranean world of darkness; or what fate, perhaps even more fearful, awaited me?"
