Loneliness is a universal human experience that has gained attention in scientific research. Researchers suggest that loneliness may be an evolutionary mechanism that promotes the formation of social bonds. Loneliness can affect brain function, perception, and cognition, leading to unique worldviews and interactions with both fictional characters and inanimate objects. These studies demonstrate that loneliness is not just about the absence of others, but also a yearning for connection, highlighting the fundamental importance of social connections in our lives.
