God once said in the Bible: If dreams don't come from God, don't care. As for your personal dream, if it really comes from God, God will naturally reveal it to you, and often the dream revealed by God is related to the future of a country and a nation, such as Daniel's dream, Joseph's dream, Samuel's dream and so on. So you can compare your mask dream with it and ask God for guidance.
In addition, everything in the world comes from God, and even when people dream, their functions are the same. In this sense, your dreams must come from God. Personally, I think as long as your thoughts or dreams can make you love God and others more. As for where they come from, you can put them aside first.
