Proving your existence to another person is impossible

Hello, sorry for the wait, I forgot about this website for the past two days, because life happened. Still happening in fact but I need a break from it. "Actually, it depends on whether the reader is capable of lucid dreaming." That is a valid point, and many people DO know when they are dreaming. However, this does not mean that only one layer of a dream could exist. Lucid dreamers know at least when they are in the layer of a dream past this one if this is a dream, but how can we be certain that that applies for all layers of dreams? Maybe it is impossible to know that you are dreaming, and you think that you are dreaming when you are in fact dreaming inside of another dream. "Dream: Takes place in the subconscious, usually when asleep. Pretty much anything can happen, and if you're capable of lucid dreaming, you can do anything. Dreams usually don't take place on a specific date, and you most likely aren't in a real place." That has a lot of usage for the word "usually". When you dream you are convinced that you are awake, and if awakeness is really a dream then why shouldn't it work the same way? How do we really know the difference when they seem the same? "Reality: Once you wake up from a dream, you can be certain you are awake, and in reality. You can't do anything you want, as physics act as a boundary. Reality takes place on a specific date, and you definitely are in a real place" I have already pointed out that dream layer 1 and 2 could be different, maybe physics in the "real" world aren't how the truly real world works. Also your statement of being in a real place is just an assumption. It has nothing to back it up anymore than saying that dreams are also a real place. "I concede I cannot prove to you I have been seen, but that's irrelevant. (rest of paragraph) and I have shown that I interacted with other people. These people do not know that you exist either. All they know is that their brain is processing certain colours and sounds, which may or may not be real. They could also be dreaming for all they know. "What? I would like Pro to explain how a non-existent being can speak, or even type. This doesn't make sense." Riiiiight, that was stupidly worded on my part. If this is indeed a dream, then how can anyone know that the people on the other end are not simply their own brain making that up, and therfore themself? It is easily possible that that is so. Rebuttal to point one I have already proven that your aquaintances, if they too are not a dream, do not know if you exist. They merely suspect so. It has not been proven. Rebuttal to point two These visions of humans that we see could also be our own brains. You don't know who is real, who isn't, or even if anyone is real. Again, if this is a dream, then all of those things you see are being invented by your mind, so they are an integral part of you, not their own entity. YouTube is your brain, Edison is your brain, bacteria are your brain, EVERYTHING could be your brain. Please do avoid innuendos.... But a dream can cause the sense of touch to occur, therefore touching humanity does not prove its existence. Also, just because humanity exists does not mean it exists in this layer of a dream. If it is true that each person is alone in this layer of a dream, so the only person in the dream world, then that does not mean that humanity does not exist in the real world. Added argument: Have you heard of the experience machine[1]? It's a concept of a dream-like machine, that would be perfectly designed to prevent you from realizing that you are not in real life, and it would be pre-programmed so that you would get to "do" whatever you want. We would not know of our aquaintances non-existence if we were in this machine. Source [1] http://www.uky.edu... P.S. Smiley face! :)
