Even if you dreamed of one of the most peaceful ones though, a brachiosaurus, these dreams still have a sense of power about them because of how large and majestic dinosaurs can be.
A dinosaur is a prehistoric organism that lived a very long time ago and was known for being able to rip the head off of just about anything. Of course this was only the carnivore dinosaur. There were many dinosaurs that had no interest whatsoever in eating flesh. Some of them much preferred to be chained up and just eating a large bag of spinach every now and again. But people in every day have no contact whatsoever with dinosaurs. In fact the closest you can get is if you are a museum curator but even then you are still going to be struggling with the fact that these are just bones and represent a living organism but cannot become one.
This is the truth about the dinosaur. What does it mean to dream of a dinosaur though if you can never have contact with one? Well a dream about a dinosaur has to do with danger. Despite the fact that dinosaurs were not all dangerous, popular perception of them paints them all as fearsome creatures ready to kill you. So if you have a dream in which you see a dinosaur it means that you are ruthless and intimidating. It means that others have cause to be afraid of you and you should not be unwelcome to this idea.
