The goose and geese can behave like guard dogs who make noise to call for attention, when strangers are at the door. Dreaming of geese, if it follows this meaning, indicates you can expect new visitors.
Other trivial meanings that deviate from this dream interpretation are:
Geese are fowl that search for food on ground, or in the water. Hungry geese indicate they are unable to fend for themselves. This type of dream imagery indicate dependency and self-centeredness. If the goose or geese are already onto you for dependency, it means you have to watch out and extricate yourself from this parasitic relationship.
