Dino Dan ghost theory is a theory which claims all the dinos we see are actually ghosts from when they were alive. here's the proof. Several times in the show, we see the dinos interact with real world objects, even though the dinos are not real.

More examples include: a dromaeosaurus steals cory's cory dogs, a diplodocus steals the teacher's celery, a t-rex crushes dan's mom's flowers, a compsognathus destroys dan's mom's flower garden, 3 dinosaurs destroy a snowdino, several dino bones/ feathers are left behind. all of these examples are only a fraction of
