I haven't, but when my daughter was two years old I really believed that she saw something. My husband worked nights and we had a newborn son. One night while up with the baby, my 2 year old daughter wakes and comes into the living room. She points into the kitchen and asked me, 'who's that lady?" She just kept pointing into the empty kitchen telling me, "Mommy that old lady is sad".
A month later she did the same thing but this time she said there was a little boy in her room who was crying. She would say, "mommy make that boy stop crying". I thought she meant the baby who at the time was actually not crying. She kept on and on and was so frustrated with me and the invisible 'boy'.
Needless to say, this skeptic believer as I like to refer myself, packed up diaper bags and headed over to grandma's to spend the night.
She talked about the little boy for a long time. One day I saw "Sylvia Brown" on the Montel Williams show. I told my daughter to tell the crying boy, "Just go to God, Its going to be okay, Go to God and you'll be okay". A week later we were in Walmart and I heard my daughter say to no one - "It's okay little boy, Go to God - don't cry"
She never spoke of it again. I still get goosebumps thinking about it.
