A Dream (mostly) Unremembered

Last night I had a very vivid dream (if you considered people telling of their dreams the height of self-absorbtion, feel free to skip). Upon waking from it, I thought "what was that all about?" and the answer came "It was a water initiation." As it was still the middle of the night, I got up and went down stairs to write down the dream, but by the time I got to the kitchen, most of it was gone. All I remember is that it took place in a large space, if it was indoors, I was unaware of any walls. A largish group of people ( 20 or so) many of whom I felt I knew. DH was there. A silver vessel-not quite a goblet, not quite a chalice. It was my initiation. I woke up after it ended, as there were congratulations. I don't remember anymore. Frustratingly enough, I remember remembering more. And, aside from DH and myself, I have no idea who any of the other people were, nor anything of the ritual itself.

Googling "water initiation" gets me 3 pages of Buddhist websites and information on water and magnetics, water and building, water and chemistry, and a few listings on baptism. So, more indepth, other than google (at least tonight, in the cold basement) research is called for. I vaguely remember some mention of this in a Dion Fortune book (but then I only vaguely remember anything written by Dion Fortune), so perhaps that is the direction to look in, first?

Tonight, during meditation, I tried to re-enter the dream. I had no success.
