When you walk into a room where an infant is and it reaches out to you, the baby can't decipher near and far yet. In its reality your right in front of it and it reaches assuming it can touch you. In life, people and experiences teach us right, wrong, real, and fake this sets the rules for “reality”. But in your dreams specifically lucid dreams you make the rules, your interpretation of real changes. You have the abillity to break the rules that have been programmed into your brain. In my opinion reality is only a blanket of perception relative to your mindset meaning Real is what you make of it "dreams" or not. (A Brain in a Vat)
