In these movies which obviously made an impression on me the native Americans (usually played my white actors in red face or sometimes Chinese people) were pictured dancing around making rhythmic pow wow noises, doing the previously described hand gesture, and yes, DANCING rather wildly about the place perhaps in circles. Likely also sometimes including drumming and other chanting noises. On the night in question, I did omit the possibly important dancing part. These movies weren't saying that such scenes literally meant native Americans, but rather there was that stereotypical association established with their pop cultural depiction. At least this is how I remember it. I did do a lot of drugs in my hippie phase. That was well before my turquoise bolo tie phase.
