Shamans have traditionally worked on this reclamation by practices involving ecstatic trance and journey work - and most importantly dreaming. Because it is during dreaming that the barriers most easily are crossed, but the conscious mind, or reason is always there working against it. Reclaiming an awareness of the connection to the universe. In any place, in any time - makes sense. Place and time are concepts that only apply to the intellectual body they mean nothing to the rest of us.
Culture gives reason it's gunpowder.
Now let's go even further down the shamanic road. Can you go far enough into your dreams to dream yourself back into the world. The rational mind is a very tricky partner. It wasn't the dreaming that killed him though. I frequently have dreams that take me into events in the future from my own perspective - premonitions.
