Visions...

Ok,
This might sound weird, but I have never experienced something like this in my life... If anyone has any insight for me, I ask that you please answer some of my questions.
This afternoon as I was spending some time with God, I was asking God to reveal what I was supposed to do with my life. I have been spending this year finding my purpose in life and it was a question that I asked many time's, but I never got a response.
Today He gave me a vision. It was a very clear vision.
Out of the corner of my eye I saw I glow grow larger and larger until I saw a face, two faces. It was of me sitting and playing patty cake with a little girl. This girl was only a year or so old and looked just like me. She had beautiful red curls and crisp blue eyes. Her chubby legs peeked out of a little yellow sundress. She was filled with smiles just as I was. I felt this wonderful warmth come over my body. I felt joy and tears welled up inside me as I watched us play on the quilted blanket.
I closed my eyes and I could still see the two of us on the blanket. I asked God what this was and He answered "Zion".
For though's of you who don't really know me or my husband, we are unable to have children. We have been trying to find a way to expand our family for almost eight years now and we haven't found the answer. This last spring we physically gave it to God with a bunch of loved ones surrounding us. We felt led to work on a marriage more then or fertility problem and we've been walking on clouds ever since.
My son has never given up on having a sibling, but Sheldon and I have felt enough comfort that this problem has been left in the dust. "PRAISE GOD" Is what I've been saying. God has freed us completely from our pain.
Going back just a little... During the years that we've been trying, Sheldon and I had found a name that meant a lot to us. You want to guess what it was?
"ZION"
I was filled with so many questions after the vision left me and God is staying quiet.
I know a little about reading dreams and seeing visions and I don't know if this really was God talking to me. I have heard that the feeling that you feel during a vision can answer a lot of questions... I was happy and satisfied and as I said earlier, I felt a warmth come over me. If I was feeling scared or angry, I would know that this was Satan trying to destroy the new content me. But I didn't feel the anger...
What is this?
Is God talking to me?
Am I imagining this all?
If you have any answers on how to read visions, please let me know.
If you don't, I ask you to pray for me that I can finish this conversation with God and see what he's saying.
