"Dreams pass in time..."
In Revenge of Sith, Anakin says "We don't need his help" when Padme says they should get Obi Wan's help so they could find out what to do about his dreams of her dying in childbirth. Anakin, in the movie, refuses to do so although in the novelization he contempelated getting Obi Wan's help. I see the movie as more canon though, so this is what I'm basing this of off. So why doesn't Anakin want his help?
Well, it's because Obi Wan said "Dreams pass in time" the last time he needed to know what to do about the dreams/visions he was having about Shmi getting tortured by the Tusken Raiders. Anakin, for once, followed Obi Wan's advice and the Jedi Code but that ended in Shmi's death. If he hadn't followed Obi Wan's advice, then he might have been able to rescue Shmi on time. He's afraid that if he takes any more of Obi Wan's advice again, that will probably end in Padme's death also, which is understandable. It's also why he partially blamed Shmi's death on Obi Wan---if he hadn't listened to what Obi Wan said, he would have probably rescued Shmi earlier, long before she was about to die.
