A thought left to itself will always move. Under no law of physic it will disperse and drag you with it in many directions. A thought left to itself will pass like a wave through the matter of consciousness. There is no beginning to thinking and only a testimonial end which for me is no experience. Beginnings and ends are just a matter of opinion though. When the film ends the dialogue begins. When the dialogue gets exhausted the silence begins. There is always something to follow.
