I keep seeing these girls in my dream!?

One girl is very young. She has dirty blonde hair that is curly and short, and often wears an orange dress. I see her the most. The oldest one is a little younger than me, (I'm 13), and she wears a pink dress. But in one dream I saw her in green and blue. She has straight brown hair. I see her a lot in some dreams. Then there is the youngest one, I see her rarely, she looks a lot like the the girl in the orange dress, but she is younger and wears a yellow dress. All the dresses have the same design, sundress with white fleece. The girls have blank expressions. They live up my street in the dreams. They often are seen walking down my street/sidewalk. I see them as sort of annoying, and they always are trying to get me to play with them or follow them, and I will, but I wake up before we get there. These girls appear in my dreams alot, and I see them as friends. I always hesitate to follow though, because I find them annoying. Who are these girls, why are they appearing in my dream? Thank you.
