What is the meaning of the skies in Magritte's work?

In Magritte's work, the skies often represent a sense of mystery, the unknown, or the subconscious mind. They can also evoke a feeling of infinity or vastness, prompting viewers to contemplate deeper philosophical questions about the nature of reality and perception. Magritte's use of the sky tends to create a surreal and dreamlike atmosphere in his paintings.
