You'll have a location in space, and a time. So the coordinate tells you "where and when" to find an object. If you add matter as a coordinate, how is that going to change the location? Try to define that, and you'll see why it's not a dimension.
Ok, so why do they collide? Yes we can establish where they collide and when they collide, but we do not know exactly what makes them collide. Why don't they just pass straight though each other? This is partly one of the reasons for my bizarre theory. What is your arguement?
