I think that what SOL and Abstract say is absolutely true. I know for certain there are different personalities within myself that come into play in any given situation. Possibly co-conscious DID? My husband even relates differently to my different personalities, depending on my mood or behavior. We even have different names for some of my aspects; i.e. today I am so and so, the next day someone completely different. We sort of make a game of it, find humor in it.
I have a silly, whimsical, impulsive little girl self....a child who takes nothing serious and only wants to play, be cuddled, and make others laugh. I also have my practical self....the adult who gets things done that need to be done, is a responsible, caring mother and wife. I have an aspect that is a survivor.....an angry victim who can't get beyond pain and suffering, that has no tolerance for the abusive, greedy, gossipy, selfish people that I see in every day life. Lastly, I have my mystical, spiritual self....someone that believes in miracles, a higher power, and has an obsessive passion for trying to make the world a better place through the power of love, peace and harmony. None of these aspects blend into a whole, but are very distinct and separate from one another.
