They are probably all different people who agreed to become a clone soldier, once they were set-up by having the tech. & etc. put in & on they're 1st body then were deployed off into battle then once they are killed they're conciousness is sent to a new clone body that doesn't look like them, basically a default body, to return to battle in & from their they constantly go to default premade clone bodies but they are still themself. Or they leave they're 1st real body in they're quarters, switch to a default premade clone body then go into battle then use default bodies till battle over then switch back to they're 1st body. (They can switch bodies possibly in The War Room prior to deployment.) Or they have alow of custom made bodies of themselves and use the custom ones outside battle and the default bodies in battle. But regardless they are themself. As for dreams if they're in either body then they should be able to dream, dreams are afterall natural so long as you have a brain & body you probably dream.

That's a very good question. Do clones dream? What do they dream of? Do they dream of their past? Are their pasts even their own anymore? Do they dream of death? Of untold amounts of blood spilled across a hundred thousand battlefields? Is this carnage they have caused even considered their own anymore, or is it ascribed to another? Are they really who they started as, or just another entity born into the state of something that came before them? Who's life do they live now? Can what they live now even be called a life? Are they merely a shadow of their former selves, with something irrevocably lost with each death?

Oh clones. You give us such wonderful themes to play with.

My clone dreams of chimichangas...of which he will never have and an intense burning desire to take of his suit, and see his own face. My clone is very deep...and crazy...and hungry.
