Any part of a house usually represents a part of yourself (dreamer = house). The attic is the last thing built. Consider the details of the dream and try to figure out what your unconscious is trying to tell you. Some believe that the attic symbolizes the higher self, or best self (i.e. the self that is in contact with the eternal). Others think that the attic symbolizes the sum total of your life’s work or it may predict how well you will do in old age. If the attic is full of “neat” stuff, it may imply that you are accomplishing wonderful things and are living up to your potential in this lifetime.
