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 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.
My interest at the moment is to use my dreaming self (which I also access in shamanic journeying) to engage with the Earth. In my waking rational life I often forget about the Earth, or I get worried or confused by contradictory information. With my dreaming brain I can have access to powerful images of what is going on in the Earth, from day to day.
