Biocentrism says space and time are tools of the mind, and dreams seem to be only further proof of the truth of this statement. If space and time were really external and physical as is popularly believed, then how would it be possible to create something absolutely indistinguishable from them within the confines of one’s dreaming brain? We think that our experiences at night are only dreams and that they aren’t real. But dreams and what we perceive as reality are basically of the same nature. By following the implications of quantum mechanics in an unbiased way, we arrive at the unification of everyday reality and dreams.
