And the ugly, thin cows ate up the seven attractive, plump cows. And Pharaoh awoke.
Genesis 41:4

Cows don't eat cows. Grain doesn't eat grain. Dreams and visions are almost never meant to be interpreted literally. If they are sent by God, then the various elements will usually represent something other than what they appear to be. In Joseph's dreams, the stars weren't stars, and the sheaves weren't sheaves. In Peter's vision, the sheet wasn't a sheet, it was the world; and the animals weren't animals, they were people.

Joseph and Pharaoh both dreamed twice. Peter's vision happened three times. If a dream repeats, it is more likely to be of a prophetic nature, but that's still not a guarantee. If it doesn't repeat, it's probably not prophetic.
