I don't think you're crazy, and I do believe what you're saying is true. I also think that you should be aware of how dreams work, which I think you are, and factor some of that into your 'feelings' sometimes. Also things do change in our lives, as we get older, so it's quite normal for something different to happen, even though it feels odd because it never happened before. It could be a new development in your subconscious or psyche, that seems more scary thatn it is because it's new.

By the way, have you ever had one of these premonition feeling where nothing happened, or at least nothing as bad as you were expecting?
