Dreamspeaker (1976, full movie)

DISCLAIMER: very little in the way of hollywood sensibilities and production values seeing it's canadian, made for tv AAANND the 3 main characters die in the end (including a reasonably accurate depiction of a native tree burial and a convincing scene regarding the *SPOILER* 11yr kid hanging himself....oh, and the mute one blowing his brains out while at it):
