I saw this somewhere between the mid and late 1980s on TV when I was very young. Not sure if it was a movie or TV episode. No idea when it would have originally come out, but it was definitely in color. It had a horror tone to it. I remember strong visuals of a pond or lake containing lilypads. There was a little girl in it, along with some kind of “being”. I don’t remember what this being looked like, and I don’t know if it was alive, dead, undead, or reanimated. I think it may have been human, and I want to say dead but came back to life, but I don’t know for sure, and I just can’t picture a face. The gender would have been male. I think this “being” came out of the pond, and the only other thing I remember was that it gave the little girl a flower (or maybe it was the other way around, and the little girl gave the being a flower). For some reason, whatever it was, the girl did not seem afraid of it. It was almost like a fatherly figure. I don’t remember any dialog, and I don’t know what ended up happening after that.
