thunderbirds younger brother

I had a crazy dream/vision just over 2 years ago, i was in my local mall and as i was crossing the parking lot i noticed 2 native men doing a dance and they had long staffs (about 6 feet long) and they were twirling them around really fast. anyway, i entered the mall and they were inside putting on a show for everyone to see, then they combined and turned into 1 man, he looked really impressive, he had no shirt on and he was physically fit like he worked out all the time, and he was covered in either sweat or oil (not sure) and he was wearing light grey down pants, or maybe his legs were covered in down like he was a bird/ anyway, he continued this awesome dance with his staff and he kept changing in size, sometimes he was about 5 feet tall and then he would be 20 feet tall. so while all this was going on all i can remember hearing is a chant, people wear chanting the phrase "toom-bah-cha" over and over again to the beat of a drum. then i woke up. about 8 months later i was looking in book on north westcoast native art (canada) and came across the description of thunderbirds younger brother and it was so weird cause it was the guy in my dream. until then i never knew thunderbird had a younger brother or his name.
