Had a dream of a two friend. The one is my best friend the other is a recently no longer friend.
Went onto an elevator by myself and turned around and a woman and little girl were holding hands, I knew they were ghosts they were both dark, you could see their faces but they looked like they were convered with charcole. I spoke the works "Oh my God" and the little girl repeated it back to me. I got off and was walking down the hall and was pulled into a closet and I saw a bright white little blond haired girl smiling at me. I asked her what was going and and she replyed "you'll understand soon enough". I kept repeating myself and she kept repeating the answer. Next I was talking to my ex-best friend. She kept saying "Im coming with you and I kept say No because I no longer am friends with her. She said she was coming anyway. WE got on the elevator and the little bright white girl was standing next to me holding my hand. When I went to get off the elevator the little girl would not let go of my hand. I then am off the elevator and the other woman and little girl (the dark ones) and in front of me. The little girl looked up at her mom and the mom said "she'll understand soon enough". My ex bestfriend was gone at this point.
I am trying to understand if this is a message or warning of some type. Anyone have any ideas? By the way I have had dreams about this little girl in the white before. I cant remember what but I definetly know I have dreamt of her at other times. She was transparent the other were not.

To add to what L4L says,

White - White is a feminine color. Symbolizing virginity, purity, well earned success, honesty, virtue, innocence, peace, happiness, joy, transformation, cleanliness, dignity, awareness, clarity of mind, hope, and light feelings, but also emotional coldness and immaturity.
White in a dream might possibly be a reminder to resolve special situations and problems.

Ghost - In general, ghosts symbolize aspects of yourself that you fear. This may involve a painful memory, guilt, or some repressed thoughts. You may be afraid of death and dying. Alternatively, ghosts are representative of something that you feel is no longer obtainable or within reach. It indicates a feeling of disconnection from life and society. This dream may be a calling for you to move on and abandon your outdated modes of thinking and behavior.

Elevator - Going up and down in the elevator may symbolize going from one state of consciousness to another. Messages from the subconscious may be accessible. The elevator may simply represent the "ups and downs" of life. If you are ascending, then you may perceive your current situation as optimistic and moving upward. If you are descending, you may be experiencing some negativity and helplessness.

Good Luck!!
