Yes, many dreams have significance in that they bring hidden emotions, tensions and stress to conscious awareness. It is quite common to find the solution to problems through dreams, as well as intuitive insight into one's personal relationships. Modern psychology has a long history of looking to dreams for insight into the unconscious mind. See attached links for further information.

The number 80 does not have any universal significance. But in your own dream, it might have some significance for you; it may be a room number, a house or street number or a specific amount of money that you owe or perhaps is owed to you. Other details or the context of the dream might provide more clues; where does the dream take place? at work (cubicle #80) or at school (lecture hall) or at a shopping mall ($80 purchase.) Unfortunately, number dreams tend to be random, and even if you identify the source of the number, say, the street address where you grew up, it might not have any special significance to you now.

Dreaming of a seagull has no particular meaning unless other elements in the dream give it some sort of significance.
