Yep...that's what it is, and it IS dangerous to those unprepared.
Drawing down the Moon is a form of Aspecting. In Trad ritual, you are Aspecting the God/Goddess as HP/HPS, though usually not to a major degree (no pun intended). Sometimes you just get the "in the groove" feeling, sometimes you really feel Them, sometimes They speak through you. But there is Aspecting where you surrender your individuality to the particular Deity (usually in trance work) and they temporarily possess you. I haven't tried it myself.
This form of Aspecting is done in Santeria, Candomble, Voudoun, etc., for example. Done properly in context, it's a fundamental part of their ritual. The whole idea of a successful ritual is to have one or more Orishas speak through those possessed. I've drummed in a Santerian Circle, and seen it in action - and as the drummer connected to a particular dancer, felt the connection myself. But it is not something for untrained idiots to be mucking around with. A Reclaiming group here I hung out with some (two then-band members ran it) did a form of Aspecting in some of their rituals. But after they saw nothing wrong with having some Newbie with three months of training ask to do it in their Samhain ritual, I cut my ties with them - because they were clearly the kind of irresponsible folks that would hand a young child a loaded handgun. Their comment was, "Well, either it won't work, or he'll learn his lesson." AAAUGH!
Another form of Aspecting is used in CM in several different ways, but I won't go into that here. This ain't a CM site. But that kind of stuff is exceptionally dangerous to all but the best-trained Adepts (of which I am not one).
