Final answer:
The passage most strongly supports the idea that Freud believes analysis of any dream leads to sensitive personal topics, requiring discretion. This aligns with his broader theories on dream analysis as a means to access the unconscious mind and its buried thoughts and feelings. The correct answer is option: C. Freud believes that close analysis of any dream will eventually lead to sensitive personal topics.
Step-by-step explanation:
The idea best supported by the passage is that Sigmund Freud believed close analysis of any dream would inevitably lead to sensitive personal topics. In the provided paragraph (paragraph 21), Freud discusses the inherent difficulties and the need for discretion during dream analysis. He indicates that whether examining his own dreams or someone else's, he would encounter the same challenges that require him to maintain privacy, suggesting the invariable path to uncovering deeply personal issues.
Freud's assertions about dreams reveal his theory that dreams are a window into the subconscious mind, often touching upon repressed memories and desires which contribute to inner conflicts and neuroses. As dreams often delve into the latent content, or hidden meanings, they tend to reveal parts of ourselves that are sensitive and private, therefore necessitating careful handling and confidentiality.
Therefore, option C, which states that Freud believes that close analysis of any dream will eventually lead to sensitive personal topics, is the one most aligned with the essence of the passage and Freud's views on dream analysis.
