Last night I had a freaky dream, I know, I'm fecked up in the head, I'm not going to go into the specifics, but can anyone tell me if they know of an anime which is something even slightly similar to this;

I wouldn't know exactly the specifics, but this is the thing's I remembered (Bad grammar is win)

There's a girl, almost like a puppet, all cheerful and stuff, but when in water (Atleast I think it was water) she splits into 3 girls all older (Teens maybe) and wearing black and is actually evil, The girl was a lure.

As I said, I'm fecked up in the head, that's all I remembered, since I'm a bit of a psychologist I'm trying to find the symbolism behind this. Any help would be appreciated

EDIT:
oh I remembered, the 3 are ghost like, I.e throwing shiz at them won't really work :P
