Maybe not answer, but perhaps to explore ………
I think that there is a little bit of a misconception about what a ‘Shaman’ is, as the word is generally understood to mean ‘Siberian healer’.
Not all Shamen are healers.
Basically - the Shaman serves the ‘Source’ (the Shaman was awakened to) by practically serving Others in whatever capacity the individual Shaman is most apt to serve.
So some can be healers, others are psychopomps, others are seers, ‘prophets’, keepers of cultural mythology history/storytellers, teacher/guide counsellors, ‘magicians’ etc.
Dreams and visions about the past or the future is very common in shamanic cultures and one doesn’t need to be a shaman to see those.
I think, what stands out in Siberian Shamanism is the use of Trance.
The person’s totem perhaps? Power animal?
A curious thing happened when I did a journey through my chakras:
Spontaneously an animal appeared with each chakra – and I had never heard of such a thing.
When perceiving ‘energetically’ one comes across a lot of things one has never heard of before.
Yes, I always research the stuff later on as well ……..
Of course! it is possible for a Westerner, it is just that in Indigenous cultures people are more readily aware of ‘energy-fields’ - though not all of them either.
But I must admit, I do discern who is indigenous & who is not by people’s awareness of energy-fields.
I tell you a story.
Last town I lived in, there was this slightly ‘Asian’ looking guy (but in Oz you have got heaps of those, so no-biggy).
This guy however captured my attention, because when walking the streets, I suddenly saw him in front of me clear as day
– only to walk round the corner – and there he is!
This happened like all-the-time
, so finally I asked him who he was and where he came from.
He is a Canadian Native and yes as we compared ‘notes’- he innately is very tuned to ‘energy-fields’.
Best not ask others, intend to find the answer and allow your guidance to find the way.
But do you really want to know?
The intent to serve, to heal, I think is enough – best not get ‘greedy’ and get ahead of ourselves.
Your capacity to heal will grow in its own pace and in its own time and situations to help you are ready for
will spontaneously appear if you allow space for that kind of 'magic' to manifest …..
