My Dream

I had the strangest dream last night. I was at a carnival place with games where you pay a dollar for a turn and then lose, but you really want something, so you keep paying until you end up paying more for the toy then if you had just straight out bought it. Whatev, anywho, I was playing a game like this for a while and losing badly.
There was a little girl who was a swimmer there. She was a resent orphan. She was really young, like 6 or so, and very small. She was looking for a place where she could go swimming but all of the places she found, she needed an adult to go swimming with her and they would not let her in on her own. An adult counted as someone who is 18 or older. I offered to go swimming with her. So, she began looking for a place to swim. She was afraid and alone and I wanted to protect her. She was small for her age.
This is weird because of the dream that I had a little while back about this same girl. I had the same feelings towards her. Who is this girl? Why do I keep dreaming about her?
