I think that when you go on a shamanic journey, you're allowing yourself to have much more access to your unconscious or your sense of connection within the universe, whatever you want to call that. You've accessed places in your brain that you don't normally. You're still there - it's your brain. But you have access in a way that you normally don't. For me, doing that felt like being in a new environment.

I think the neural pathways in our brains affect what happens in our bodies, and so can alter our health.

I think both science and art are impelled by curiosity: What's really happening? How do things really function? How can I really engage with the world around me? These are questions that artists and scientists both ask.

Stories that are real, that create you, rather than be created by you, are powerful.

We forget most of our dreams because we don't have access to those parts of our brain once we are switched to wakefulness. But why we evolved that way is a puzzle to me.

A recurring dream probably merits close attention. Something wants you to pay attention.
