What a cool dream! I love the empowering ones like that...they're very rare for me. I do have dreams where I can levitate down stairs: like, I just decide to not land when I step down, and then I can float all the way down in one, long, floaty step. It feels so real, I'm bummed when I wake up and I can't actually do it
My 2 cents:
Perhaps, since they were the aggressive Salties, they may represent aggressive/violent people or forces that you subconsciously know you can "rise above" and live your life without them dragging you down, and around...as it were
