The quote expresses a deep discomfort with intruding into others' thoughts and memories. The speaker feels that being aware of someone else's inner world without the ability to filter or block those revelations would be overwhelming and distressing. This reflects a respect for privacy and the natural boundaries of personal thoughts.
The context is drawn from J.D. Robb's "Ceremony in Death," highlighting the character's struggle with the implications of psychic abilities that allow access to others' minds. This struggle underscores the potential emotional pain involved in such invasions of privacy, emphasizing the desire for control over one's own mental space.
