Should a rice dish contain water?

When I prepare rice in my rice cooker, and I put the rice in the fridge (since I can't eat it all at once), when I take the rice out later to heat up another portion to eat, I notice some water in the rice container. Does this mean that I have not cooked the rice correctly, or is it normal? I use two parts of rice with five parts of water, and let it cook until the rice cooker shuts off on its own. I add some curry seasoning, butter, spinach, and a couple eggs (just before the cooking is finished), if that makes any difference.
