Ideas...

• 'Glamorous dead' - beauty of the dead body.  Shoot idea: body in grave/coffin/body-bag that then gets up (video), someone sitting on their memorial e.g. bench. Use overlay technique to keep them on the bench but leaving at the same time.
• Relationship between death and the mind - could use video and audio so the audio expressing regrets or concerns whilst imaging the body as if it had died
• Eyes - only seeing the eyes then uncovering the face to see something unexpected e.g. ugly or shocking - the eyes being the windows of the soul, beautiful eyes could be hiding all sorts!!
• Seaside - standing by the sea with the waves crashing/moving, or hair/clothing moving.  Hand coming up out of the sand 'buried alive'.  Benches.
• Being in a state of relaxation around people in public and observing reactions - body guards? Mark Jenkins style.Shoot idea: busy street in London or on the tube 
• Being in a state of relaxation and overlaying with something contrasting e.g. someone watching or stalking you and you having no idea such as the same people you commute to work with every morning etc.
• The relationship between your mind and your body when you have a difference with your mind e.g. someone with schizophrenia
