However, you mention River had a bad feeling. And I think sometimes people are warned ahead of time about circumstances to do or not do certain things.
My grandmother had a dream about one of her sons. She saw caskets of her husband, the fraternal twins, and then one of her sons in a casket.
Some family showed up that morning and my dad was elected to tell her about one of her sons dying the night before. Before he could tell her what happened my grandmother told him who had died. In my opinion, again, sometimes people are warned ahead of time about things, and I think its an attempt to comfort or warn people from the hands of a loving God.
