Dreaming of a dinosaur often suggests that you're wrestling with outmoded beliefs or attitudes that need to be updated or discarded. These ancient creatures could be a metaphor for something in your life that should be extinct but still lingers. If you're being chased by a dinosaur in your dream, it might signify fears of becoming obsolete or unneeded, perhaps in your work life or a personal relationship. The chasing aspect could also indicate unresolved issues that you thought were ancient history, yet they're back and causing unrest.
