Premonition Dreams

Croak dreams are dreams that reveal the circumstances of the dreamer's death. The episode "The New Frontier" was the first episode mentioning croak dreams. Jake was the one who had the croak dream, which was about a Banana Man and a rocket ship in space. The Banana Man had a helmet on but Jake didn't, so he started to run out of air in the hard vacuum of space. He tried to reach the rocket ship using his Stretchy Powers but suffocated. At the end of croak dreams, one sees the Cosmic Owl. Jake states that the appearance of the Cosmic Owl at the end of a croak dream is proof that it was in fact a croak dream. It is unknown if one can cheat fate by avoiding a croak dream's circumstances, but Jake says that one can't. It seems possible that one can avoid their fate with the intervention of another, as Finn interfered in Jake's croak, saving his life. However, at the end of the episode, Jake states that what happened on the episode is supposed to happen again when Finn isn't around.
