Why do I dream of you?

Sometimes I think Im dreaming, and nothing is real. Like everything is just a shadow, and everything I see is just a figment of my subconscious mind, it moves so terribly fast and before you know it its all gone, a storm of colors and sounds knocking you off your feet or disorienting you so you dont know whats what or whose who or even who your meant to be, let alone who everyone else is and how they relate to you. Its just confusing, so much so that I find myself just wanting to detach because I dont feel like dealing with it.
