Robot's dreams

Some pseudophilosophical gamers' thoughts come to me today. There are NPCs in a dream. Certainly. They work pretty similarly to a videogame, in terms of consciousness, etc. (Take it as a hypothesis, if you are not cool or gamer enough.) 

So, if we want to construct a like-human robot, we can make he/she dream, making he/she play a game, at rest, and with adaptations. She/he would always dream of/play a new game, in this case, for example.

The freaking part (of course): are we AI, and are our dreams games? I don't know, and, almost, I don't care.  However, to me, the important question would be: for what? What is the function of dreaming? I'm not a dream specialist, but I guess it has a learning proposal or something like that. 

One little deeper in the freaking part: seems some dreams are just ways to know how we will act in "real" life. There is more, of course, but this seems to be a crucial aspect of dreaming, and, in robotics, it would be useful to monitor behaviors and psychological disorders. 

If you want to go even deeper, we will find ethical issues. For instance, when we think about the reversal application. Could we access human dreams to spotlight dangerous behavior in the actual world? I think it would be too much, while for robots it would mean safety and manutention.
