Dreaming of crocodiles eating everyone

I have very vivid dreams, in this one, after doing something in a government office, I dreamed crocodiles were eating everyone.. There were these gross human (actually not human,, more like alien, or fish like) remains piled up everywhere and as I was trying to make it to my truck, they got a hold of someone else, not anyone I knew.. It was a catastrophe. I woke up after someone i knew was driving us away
