Dream of

I saw myself trying on wedding dresses, I picked a silver/blue satin gown...then the next segment of my dream I saw a 2 yr old boy wandering the street at 3am, I took him in and had him sitting on my lap with his head on my shoulder, I was rocking him I remember feeling so sad... then he was gone...I tried to find him, I questioned people that I thought might know who he was...I was showed a photo of 3 boys...the faces in the photo became distorted and I remember feeling scared/panicked, I realized the boy was a ghost that was visiting me for some reason...but I have no idea why...
