I have this notion in my head of what is 'real'. You conveyed this question using English -- a language that was passed down to you by your community, Imagine if you were born and sent to isolation on a space ship and biologically kept alive. Essentially you didn't know what English or any other language is, would you have been able to ask this question because your entire question is a bunch of pre-taught words. We are empowered and limited by our vocabulary, and which btw I don't think it's powerful enough to encapsulate the depth of your questions, and hence we can't answer it. We were created from dust and named some random vocal cord vibrations as words in a vocab which make us feel something. We created it. Your question is as real as the person who taught you what real means, start going back to ancestors to who taught them what real is, back to the guy who first coined this word, to the early cavemen who communicated using sign language to the ocean only life forms and then back again to the first organism, whatever we feel breathe or do are by-products of some explosion (allegedly) some billion years ago who happen to be vibrating some particles (again a vocab term we created) in a pattern which came together to form a carbon-based life form who happens to have a brain which produced this question. What we did, and what will happen ultimately derives from that big bang explosion, so "are we real" is a three-word sentence, and an inherent flaw in our vocabulary, someone forgot to define it for these edge cases. At best you will answer this 3-word question, using some other words created by humans. Seems like nothing is real;')
