Seeing a dinosaur in a dream symbolizes an ancient stronghold or enemy. Depending on the dream context, the dinosaur may be a revelation of God’s wonders of creation. Dinosaurs are huge masculine creatures that existed many years ago. They also represent strength.
We will be relying on the Bible as our source of this dream interpretation. There are a few mentions of dinosaurs and is referred to as behemoth. The Bible refers to it as being “the first of the works of God” and was created at the same time as man.
Look at Behemoth, which I made along with you and which feeds on grass like an ox. What strength it has in its loins, what power in the muscles of its belly! Its tail sways like a cedar; the sinews of its thighs are close-knit. Its bones are tubes of bronze, its limbs like rods of iron. It ranks first among the works of God, yet its Maker can approach it with his sword.
This dream signifies the wonder of God’s creative works in the universe. The reason God reveals this dream is to humble you as you are trying to justify yourself instead of God, just as Job did. This can happen especially if you are questioning God and there is doubt in your heart.
Brace yourself like a man; I will question you, and you shall answer me. Would you discredit my justice? Would you condemn me to justify yourself?
After God has revealed this and many wonders, Job humbled himself before Him and acknowledged his wrong and hence repented in the dust. Please read the book of Job chapters 38, 39,40,41, and 42 to understand the conversation between God and Job and the mighty revelations.
A dinosaur attacking you in a dream.
This dream represents an old system or an ancient stronghold that is attacking you. This enemy has similar characteristics to those of a dinosaur. He is strong and ancient. The old stronghold is with no doubt a territorial spirit over a nation or a powerful city.

A similar spirit is mentioned in Daniel 10:13. The prince of the kingdom of Persia tried to prevent Daniel’s answer. He withstood the messenger angel for 21 days. This showed his strength and that the demon had dominated the territory for many years.
