It really bugs me when I see people post topics about dreaming being inside an alternate would. Dreams are created by our brain, you aren't in some other reality. Maybe if dreaming was totally unstudied and we knew nothing, but that's just not the case. When people post these topics, I feel it's what they want to be true and not really logical in one sense. We shouldnt worry about why we are dreaming, because that honestly isn't important if you're just an everyday joe. Instead don't worry and just enjoy dreaming for what it is!
