In Episode I, Anakin tells Qui-Gon that he dreamed he was a Jedi:
Anakin: I had a dream I was a Jedi. I came back here and freed all the slaves...have you come to free us?
We take from Episode II and III that Anakin has a great amount of visions. Since the Force is so strong in him, and it was being manifest on its own (eg. piloting a pod-race at the age of 9, for example)...
...Was that dream a true Force-vision that was somehow disrupted by his turning to the Dark Side?
