Meditations, Part 1, Paragraphs 5&6

In meditations, part 1 in paragraphs 5&6, Descartes is talking about being asleep and being awake. He says that when you are awake, your eyes are open, your head is not heavy like when you are about to sleep, you can move you arm or finger and know that you are moving it because you can feel it. He says that when you are sleeping, these feelings are less distinct. Descartes says that the things you see in your dreams reflect the things that are real and true. D says that "...the things seen during slumber are, as it were, like painted images, which could only have been produced in the likeness of true things, and that therefore are at least these general things- eyes, head, hands, and the whole body are not imaginary things, but are true and exist." (page 61) He said that painters sometimes fuse parts together like let's just say, a human head on a horses body for instance, and we know this is false because no one in this world has ever seen that while they were awake. So, I think descartes is trying to compare dreaming to painting and art. In a painting, whatever is in the painting, came from the painter's imagination which can be anything. Painters also take the color a lot of the times from seeing things when they are awake. They paint grass green because in real life grass is green. So D thinks that in dreams you see grass as green because that is how you see it when you are awake. In dreams we see a lot of what we see when we are awake. By this reason Decartes feels and does not doubt that that is why he knows that we are awake and we do have a body and such things like time and shape do exist.
