Step 1: Recalling the Text:
In Jack Finney's 'The Third Level', Charley discovers what he believes is a mysterious third level of Grand Central Station leading back to 1894, but afterwards cannot locate it again despite repeated searching.
Step 2: Explaining His Reaction:
Frustrated and obsessed, Charley searches for the level again and again without success, and even consults his psychiatrist friend Sam, who dismisses it as a wish-fulfilment fantasy born of the anxieties of modern life. However, after Sam himself disappears and Charley later finds proof (an old, genuinely postmarked 1894 letter from Sam) that Sam did escape into the past, Charley stops trying to find the level directly and instead starts buying old-dated currency through a stamp and coin dealer, hoping to save enough authentic old money to be ready if he ever finds the way back to 1894 himself.
Final Answer:
Unable to relocate the third level despite repeated attempts, Charley grows frustrated and even seeks his psychiatrist friend Sam's opinion, who calls it wish-fulfilment. But once proof emerges that Sam genuinely reached 1894 through it, Charley redirects his effort — no longer searching for the level itself, but quietly collecting old-dated currency through a dealer, hoping to be ready to escape into the past himself one day.
