Well, that was disturbing enough to remember. The other dreams are completely lost to me. I quickly pieced together where the dream had come from. Last night I watched the movie "Rachel Rachel" (great movie!) which has flashbacks to chidhood, and echoey children's songs, and also dead children (in a funeral home). The ghost girls definitely came from having watched that movie. The asylum is from an article I was looking at two days ago, on Western State, where Frances Farmer was interned. And the eye, I'm pretty sure, is the eye of evil that looks down at Frodo in the Lord of the Rings movies (though I haven't re-watched those any time recently).
The social order of spectres is something that has been hinted at in various episodes of "A Haunting" (one of Leeann's favorite shows), and sometimes on other shows (like "Ghost Whisperer"). I was thinking about it two days ago after we watched one of those shows (can't remember the name of it), and so it's not surprise that I would dream about ghosts in an asylum who are held there by a malevolent presence. There is no scientific proof for this sort of thing, but for all we know, it could happen. I mean, couldn't it?
