When I was a little girl I had a friend her name was Jade. She would play with me and listen to me when I had aches and pains. I never realized she wasn't "real" until my brother told me that, I was crazy. My mom didn't care whether I had a army full of invisible friends, I was her 7th child and she had her arms full.
One day as I grew up, she disappeared from my sight into my ear. I no longer was able to see her, but could hear in my mind. It turned out she was my Spirit Guide.
Do you recall your invisible friend?
