How come when we fall asleep and enter a dream it's not weird?
I know, random question, but really: when we go to bed in our bedrooms in our homes, how do we not realize we drift off to sleep into a dream? I have very dreams that seem so close to reality, sometimes it's hard to differentiate... even when there are obvious obscurities like monsters for example. When I wake up, I realize it's "just a dream" despite just being in some other universe and it feeling real. Theories?
