Ghostly Waters

Ok, This is actually a Test My Zoom shot I did, aimed at the base of a fountain where the water pours over......Cool shot, but look closer........There are 3 things in this shot that I didn't place in this shot, no messing around in PS to get them there either........Mind you, there was nobody anywhere near that fountain, including me (was a few feet away myself). See if you can figure it out!
