Show your true Colours
I have a friend who lives at distance, she is someone that I love dearly. I have pictures of her in my mind and in my dream I saw two pictures of her. In one of them, she was sat on the armrest of an armchair. I could see her in green color with a white wall in the background. She was looking at me, laughing. Suddenly I woke up. What does this mean?
Well your dream creator has sent you a short and cryptic dream, likewise you haven't given me much to go on, but I'll do my best. You paid particular attention to the colors that you saw in your dream, the green color she was wearing and the white walls, green often symbolizes healing, renewal and growth, it is a color that features throughout nature, it absorbs the negative energy out of the atmosphere and releases positive rejuvenated energy. It doesn't really matter what type of green is used, but at least we know that your friend is surrounded in this positive healing energy. White is a pure energy color that translates a clean slate, new beginnings, a fresh start, etc. Therefore the symbolism from both these colors suggest that renewal, healing and a clean start is needed or at least being offered.
The armchair is a typical symbol for comfort and support, the condition and type of armchair will be helpful in your translation, but your friend is sitting on the edge which suggests that she is on the edge of something, perhaps she is thinking about something but she isn't completely sure what she is going to do as yet, or perhaps she isn't sure if the type of support that is on offer to her is going to provide for her needs or make her comfortable.
Incidentally walls can be used to symbolize barriers or obstacles to get through,your friend has to overcome her own barriers or make decisions that are complicated. A brick wall can be used to represent the notion of talking to a brick wall, but in this case the wall is white so I don't think the wall represents this, more likely it means that she has to get over her own worries and just start again, she really does have a fresh new start to make. Like a blank artists canvas she can paint her own picture from scratch, when she has allowed healing to take place of course.
You also saw two pictures of her, perhaps this represents the before and after, one is how your friend was before healing and the second is how your friend is now. Exactly what your friend has gone through I cannot say here because there just aren't enough clues from the dream, but overall her dream is telling her to heal, and that to become more comfortable or happy she will have to just sit back and relax and let nature take its course. She can start again, fresh and new and she must not stress about how it all turns out, and she must not put her own take on how the future will turn out, because the future hasn't been written in stone tablets somewhere, she creates the future herself in the now. Photographs and pictures back this up even more because they are about capturing a moment in time, once captured they cannot be changed, therefore I want to say to your friend that you can't change the past, but you can definitely change the future.
Oh, and she will probably have the last laugh.
