Hi a_Shikhs
Horse is a strong ally here in the UK, the White horse cut into the chalk cliffs of Wiltshire:

Epona and Ellen of the Ways were both associated with horses, the path, journey and travellers (in life and death). Horse also seems to be associated with the land itself.
Speaking personally, I wasn't really given an option. When I got to rock bottom both in health and depression, the doctors were useless, they had no diagnosis and I wasted for about 7 or 8 years not fully understanding why I was debilitated or how to find a cure. Only when I came across a tarot deck in a shop and then came to AT, and then started reading other people's wacky experiences which compared to my own and then reading a book which a friend sent me which expressed many of the things I was struggling to understand. Then I started to look around at the messages the Universe was showing me. Going from one clue to the next and that was back in 2005. It was like a revelation, something I had always known to be true in my soul but never had the frame of reference to acess it by.
It would take too long to go over it all but I did write a bit about it on my website.
Cat* makes a good point, there is concern over the use of the term Shaman since it is a word from the Tuval region of Siberia. Other cultures use different names and many 1st Nation Native Americans find the term offensive, if not inappropriate in connection with their medicine people (since they don't journey in trance as such - some do, some don't).
There is also a good distinction to be made between Shaman - a person who works in close connection to the Spirits to bring about healing to others and Shamanic Practitioner - western healers and non-healers who follow a shamanic path. Most people who use the term practitioner are actively involved in the healing of others.
The distinction between Shamanic and shamanistic is also worth mentioning.
Shamanic - Any culture or process using basic procedures which involve altered states of consciousness to engage help from the Spirit world. For example the Inuit people, although they may not use the name Shaman have a shamanic world view and their healers go through a shamanic initiation by the Spirits.
Shamanistic - Practices relating to shamanism or having a similar basis. For example UK traditional witchcraft has shamanistic traits such as the use of 'familiars' which are related to helping spirits in shamanic cultures.
Every person on the globe, if we go back far enough in time, pre Christianity, Pre Judaism, to the Egyptians, Sumerians, Toltec, Australian Aboriginals, Japanese Ainu, Inuit, Myans, Hindus etc, has ancestors who held animistic world views. Our ancestors are often waiting in the wings to help us see the deeper and more profound connections we have to everything. If Horse is coming to teach you, what can you find out about the mythology of horses, their significance, what they mean to you?
