Dream of child

As a child I would have this recurring dream where I was standing in a large archway looking into a very large domed cathedral type room, very dark with the only light coming from a matching archway directly across the room from me, the floor was white and black checkerbord. The room was empty, walls where smooth with some kind of painting/fresco that I could never make out. And always in every dream there was a figure, seemed to be a man standing in the archway across from me, I could never see his face or another details because the light was behind him shining in. Every time this figure would turn his back to me. Look back over his sholder and walk away......I would always wake with a metallic taste in my mouth and cold sweats.
