The symbol treat most likely means you have a hands-on healing ability, which you can use to treat others. This is the same ability Jesus uses in the bible to heal others. Hands-on healing involves channeling energy through your body and projecting that life energy into your client. If it shows up in a Halloween trick or treat setting, it means that you do not believe this is a real ability – it’s a trick. Given the society we grew up in, having that view is understandable but you need to do something to open your mind to it.
