Holy ga-freakin-zooks Erin! Having just read about your first astral experience, I can't but wonder if it's all worth it. How did that particular set of encounters end anyway? I know you've already addressed this, but if this were a book, I'd be tempted to skip to the last page right about now. Were those in fact negative entities or not? If so, was this solved through increasing your vibration?
I don't intend to start practicing AP anytime soon, but I do believe it's possible, which puts me in the awkward position of being afraid that I might get into a similar situation accidentally. What I'm probably expecting is confirmation that AP is difficult stuff, and the odds of it happening accidentally are extremely slim, which coupled with the odds of encountering such negative entities make it all but impossible. But then and again, I do already lucid dream.
