Primarily he considers existence of the external world and whether our experience hold knowledge of this world or whether this knowledge is merely an illusion. He makes it quite clear how misleading some of external sensations can be. We are never sufficiently aware of subjectivity of our own thought and senses. The only thing we directly experience is the nature of our own ideas and we do not realise how our own appreciation of certain concepts may be very different from the objective character of the external world. Descartes takes a look at memory, imagination, hallucination, dreams, predictions, etc. which he calls our (sensory awareness) as these are part of the way we perceive the external world, he doubts at first that any of these internal experience holds any truth or existence. As he is

Right in the beginning of this last meditation he is already trying to prove the existence of external object, one way of achieving this is by recognising the distinct ideas, Descartes had of external objects, they were thoroughly imprinted in his memory, he realised that the concept of these ideas could not have originated from his mind. Therefore holding the clear knowledge of these objects was a projection of other objects.

I believe the fact that Descartes returns to the doubts raised in the first meditation bring more sense to the rest of the five writings and in a way holds them together. He very effectively uncovers his dualist ideas but he does not exaggerate or make them absurd as he also continually reminds us of the great importance of the mind and body relationship. Most importantly he proves his existence and the existence of others which is considered as one of the main problems all philosophers are faced with.

Descartes is hopeful to prove subsistence of the external world (physical objects located in space), and so he returns to a very basic stage and acknowledges the existence of minds as an immaterial substance and God. He then accepts that matter exists as long as it is not a projection of his own mind or God. As Descartes previously established the existence of God as a perfect being, he therefore has concluded that God is not a deceiver. This very clear concept leads him to accept his clear and distinct sensory experiences are a result of external objects of material nature. Once these corporeal things (objects of a tangible, material nature) can be considered as self-evident ideas, they can no longer be products of the mind or God.
