Humans have the ability to shift perspective. We can experience the world through our senses. Or we can remove ourselves from our senses and experience the world even less directly. We can think about our life, rather than thinking in our life. We can think about what we think about our life, and we can think about what we think about that. We can shift perceptual positions many times over.
