If you dream of seeing yourself sitting next to the window, then such dream foretells about your wish to have a pleasurable and calm life. If you look through the window and see something you already seen, then such dream suggests to look at the situation from the different angle. The window that is wide opened shows your desire to make the changes in your life, but if it is closed you are not ready for it yet, therefore you should wait when you will prepare yourself.
