I was a little girl standing in the toy isle of some store and was looking at two boys talking about girls and I said to the girl I was standing next to that I liked girls. Then she ran to my “mother” in the dream and said that she wanted to tell her something. I said in a whisper that I was happy I told the girl because the girl told my “mother”.

-- The little girl didn't look anything like me and the "mother" wasn't mine in real life but was mine in the dream. I'm not a lesbian in real life and i'm not a little girl age wise.

When you said that you like girls, could you be referring to feminine qualities in yourself? Could you be starting to accept something about yourself that you would consider feminine?

Does the girl remind you of anything?

Being happy that the girl told your "mother" could have to do with needing approval and acceptance.

Well i do love being a girl and being all girly and i show it off and embrace my girlyness. I know my mother really doesn't like anything i do, she just wants me to wear plain sweat clothes and nothing to draw attention to me and do go out and have fun and stay at home so she doesn't have to lose me. I always try for her approval because i don't think i have any.
The little girl was cute and blonde i think, i have red hair in real life though i wanted to get blonde highlights and my boyfriend really likes blonde hair and my hair.

I am starting accept myself as a whole lately and i'm really starting to like myself and i'm a lot more open with everything.

Since your mother in the dream wasn't your mother in waking life, maybe she is the mother you wish you had, the one who understands you and accepts you.
