Yeah, salvia will give you crazy trips, I love it! Anyways, I don't think it was pcp if you only took 3 tokes, I've gotten weed laced with pcp before (sadly), and it took 3 bowls to the head before I felt the pcp, all the other times I smoked out of that bag, it was fine, but 3 bowls to the head and I was seeing forest animals foaming out of the mouth trying to eat me, very bad experiance. Anyways, if you get a chance, buy some salvia and do it without weed, salvia is great!
