vivid dreams mean something?

Ally

well a year ago I had these vivid dreams where I was pregnant, except I found out later in the pregnancy that I was pregnant and I found out from the doctor, and it was a girl, I saw the baby and everything, well here about a month ago this little boy asked me if I was pregnant with a little girl and I told him no but he asked if I was sure, than I had a dream where I already had the baby and I kept it and it was a baby girl..... has anyone else had something like this and it turn out to be true ? my friend had a dream where I had a baby and it was a girl.. has anyone had this happen to them
