Strange occurrences of kangaroos appearing in areas where they should not be are sometimes reported. Often they appear ghost-like, disappearing or hopping through walls. 

Some speculate they are aliens, or spirits haunting us from another dimension. Someone suggested animal teleportation, maybe they bounce in and out of existence. Whatever they are, these phantom kangaroos are an omen. A cryptic warning that you will soon be falling into the unknown. They seem to say: I am real and I am hoax, and so are you.

Sometimes poems seem to say the same thing. Sightings of them can be found on this site.
