This makes a lot of sense. I think I am shifting from controlling what is outside of me, which was self sabotage, in some way to managing and soothing my feelings internally.
The grey could mean not judging myself, as in the past I have gotten caught up in black and white thinking about myself. It could also mean invisibility or a way of protecting myself. Once dream I had was that I found myself as a little girl and I was all grey. I turned away from her and someone yelled at me "Oh come on...you found her and now your're worried about competition?!"
When I was about 6 or 8 years old, my mother brought me along with her to the beauty parlor. She gave me some money to go do or buy something while she was busy. I went to the Magic Shop next door and asked if they had any invisible cream...like in the Tom and Jerry cartoon. The clerk got a big laugh out of my request and I left feeling very dejected.
