I don't think dreams have to mean anything unless we give them meaning. I prefer to think of dreams as the mind shelving and filing the books of our emotional states, dreams may just simply be a way to subconsciously process the thoughts, memories, desires, and emotions we have - especially the ones we resist consciously. The dream could be your subconscious responding to your visualizations. When I visualize a lot, I sometimes dream the scene that I visualized as if it were a memory from the day. Dreams might be hints sometimes, you'll just have to trust your own intuition on it.
