To dream of a goose represents feelings about yourself or someone who never thinks they are wrong no matter what. Persistently noticing one's self as being too important. You or someone else that feels that they always have to come first because they are too important. An assumption of automatic importance or needing to be a priority. Total disregard for anything that isn't respecting you first. Ignoring anything that doesn't think you're not the most important. Believing that all decisions are unimportant if they don't benefit you first.
Negatively, a goose may reflect complete disregard for someone else's feelings or wishes because you have to be more important. Always having to appear being right even if it hurts or costs others. Lying to others to maintain appearances of being more important. It may also reflect you or someone else that is embarrassing themselves forcing their "importantness" on others when it's undeserved. Self-regard that is overbearing or dangerous. Keeping people forced to listening to you no matter how ridiculous it becomes.
Example: A man dreamed of seeing his son trying to catch a goose. In waking life he didn't want his son moving out because he felt he'd lose control of him. He was lying to his son about all the chores that needed be done first to fix the property up in order to sell it and allow his son to move when in truth he had no intentions of ever selling or moving. The goose reflected the perpetual state of cleaning and chores the father was using to always appear too important to have to sell the homes and let the son go.
Example 2: A woman dreamed of seeing a goose chasing a cat. In waking life she was using sex to control her husband. The goose reflected how she was making herself always too important because sex was a possibility if he was doing what he was told.
