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.

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

Shamanism is the oldest form of communicating and healing. It probably resides in all of us.

We dream primarily the same way that we have consciousness of the world for the same reason. Basically, that our brains evolve to simulate reality and to control what's happening around us.

I try to see what the dream might be referring to - because the information in the world is being interpreted by my brain which only has the concepts derived from our five senses. So I think of the sequences in my dream as my brain doing its very best to process information in a way it knows I can deal with.

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.

One thing I love is to stop doing. When I just STOP and start looking, I enter a state that is much more dreamy, and find I look at things quite differently. It seems like a change in scale - both very close up, and simultaneously very distant.
