The Ghost Dance (1980) 
The Ghost Dance tells the tale of a long dead warrior whose spirit possesses the body of a Native American medicine man and causes him to go on a killing spree.
The bulk of the film plays out more as a mystery, with a group of anthropology students trying to determine the warrior spirit's origins, all the while occasionally being picked off by our maniacal possessed medicine man.
Despite the performances generally being quite credible, the pace is unfortunately pretty slow and the suspense fairly lacking.
If you are looking for a dull Native American themed supernatural slasher film which seems to spend a fair chunk of its running time in the dark then this may be for you.
