The attic is usually a place for storage of excess belongings which are not immediately used, but are still valuable enough to keep. To dream of a messy attic, can mean your life is messy. If you dream of a clean attic, it means you live an organised life.
If you dream of living inside an attic, it means you are not earning enough money in life. This probably reflects your condition in your real life. You may be financially challenged and struggling to make ends meet, but have a strong attitude and can’t admit defeat. This dream can be a wake up call for you to consider your standing and make some changes.
