Do Greeks believe the soul leaves the body during sleep?

In ancient Greek philosophy, particularly in the works of Plato, there was a belief that the soul could separate from the body during sleep and travel to other realms. This idea is not universally held among all Greeks today, as modern beliefs about sleep and consciousness vary widely. However, some traditional views may still reflect the ancient understanding of the soul's separation during sleep. Overall, contemporary perspectives on sleep are more scientific and less focused on spiritual interpretations.
