288. Since God is a person, the whole angelic heaven, taken as a single unit, presents itself as a single person. It is divided into regions and districts according to our human members, organs, and viscera. There are heavenly communities that make up the district of the brain and all its components, of all the facial parts, and of all our physical internal organs; and these districts are distinguished from each other exactly the way they are in us. In fact, angels know what district of the [heavenly] person they live in.

Heaven as a whole has this appearance because God is a person; and God is heaven because the angels who constitute heaven are recipients of love and wisdom from the Lord, and recipients are images.

I have explained at the close of a series of chapters in Secrets of Heaven that heaven is in the human form in all respects.

Being "filled" means being endowed with a spiritual quality. When the material in question is good -- water, food, people who represent good things, etc. -- it means getting a desire for good and an understanding of truth from the Lord. When the material is bad -- dust, flies, emotions like despair or terror, etc. -- it means being overwhelmed and enslaved by the desire for evil and the false, twisted logic that supports it. There are a number of references in the Bible to "filling the hand," which has a specific meaning and is dealt with separately.
