To dream of a giraffe represents arrogance, conceit, or believing that you are above others. You or someone else that is seeing themselves as being more important than others. An issue where you think higher of yourself all the time.
Example: A young woman dreamed of a giraffe peering into a house that she and man she had a crush were inside. In real life she believed that she was the only one that was good enough to be with her crush.
