Going along with that idea of a “dream,” maybe you could create a collage that contains images of your hope for the future. You could include personal as well as social images of the future. Using collage, you can include just about anything you want in any configuration you want.
You may want to juxtapose certain things for added significance: i.e. a peace treaty next to a marriage certificate or images of peace over Palestine/Israel. And since you’re using a collage, it’s a double meaning on the concept of “dream.” When you dream, concepts can be grouped together based on any connection. They don’t have to occur in the same place or in linear time. So, your dreams for the future could take the form of a dream. In that case, you could include imagery that is dreamlike or surreal. This could open up possibilities with the visual aspects.
Why not examine the word dream. It is thoughts, emotions, sounds, that occur when we sleep. A dream could be something bigger than life, or something over the top. It could be a goal someone sets that may be difficult to reach however, if it were reached, it would be amazing. Therefore, when deciding what to do for your art project, why not project yourself 5, 10, 20 years into the future and imagine what kind of dream you would like to see realized in your own life, or for the world. Could it be world peace? An end to world hunger? A home and family for you to enjoy? You decide what dream for tomorrow is in your heart and go with it.
That sounds like a really interesting art project idea actually! From my point of view, if I were doing a project that had the same theme, I would lay out a really long horizontal piece of paper and use either graphite pencils or colored pencils and draw myself sleeping in bed with a dream bubble coming out of my adventures in the dream. Luckily, in a dream, you can do whatever you want or be whoever you want to be, so incorporate that and be creative!
