To dream of a pterodactyl dinosaur represents feelings of fear or terror of other people enjoying thinking it’s easy to make you feel stupid. The terror of truth, facts, or problems easily catching up to you. Fear of something that has no problems finding you. Fear of starting something with consequences of explaining. Fear of avoiding something that ignorantly believes it understands you when it doesn’t. Fear of flying.
Example: A woman dreamed of a pterodactyl giving her an egg. In waking life she was fearing flying to a another country to take part in a very foreign type of spiritual ceremony. She was afraid that both the cost of the unusual trip to the foreign country and the spiritual ceremony would make other people have an easy time laughing at her.
