Synchromysticism is the idea that everything is connected. It's like when you are looking at a picture and you see something familiar like a person or an object that is related to something else in the world. For example, maybe you see a painting and you recognize the person in it. That could be a sign that different things in the world are connected and that maybe they have a hidden meaning. People who believe in synchromysticism think that these connections can be used to uncover mysteries and can help us find out more about the universe.
