I am currently preparing an article about this dream. I’ll provide a link once it’s done.
As for the interpretation. First, think about what a teddy bear means to you personally. Is it a sense of security, comfort, childhood memories, or something else? When someone steals something from you in a dream, something important has been taken away from your life. If a teddy bear means safety for you, you may feel threatened in your waking life. Or something may have taken away your comfort in life (e.g., moving, workload, etc.)
