Can you prove to me that you exist..?

My argument is more on the side that I might not exist. I feel as if I’m simply a person in a dream. In this dream I am just a face walking by. I don’t think that my existence is important. However I know that I am real. I feel that I am real because I feel emotions such as pain. If proof is what you want try walking throw me I’m sure you won’t succeed. However you can’t use that as evidence since you can’t actually see me. That is all I can offer.
