There are various types of holes that a ghost may have in their astral body. I will explain what all of these mean in Lavenderism. When you are practicing necromancy, these holes will give you hints about the ghosts you are working with too.
The first and most obvious one you may be thinking is bullet holes or injuries a ghost may still believe it has. They cannot keep injuries after their death, so these are self-imposed by the intranquil soul believing it still has the injury or not realizing it has died, wondering how it lived so long with its wounds.
Holes in the chest that are circular tend to come from ghosts who feel emotionally empty or lonely. They may have been lonely in life, had chronic loneliness, or were unable to make connections with people or maintain friendships.
Holes in the chest in a heart shape represent an issue with finding romantic partners, soul fragmentation from trauma, or a lack of satisfaction in regards to romantic life before the ghost died. This is seen in many who die without experiencing profound romantic relationships if that was a large aspiration for them.
Navel holes are in the shape of triangles, and usually appear where the ghost’s belly button would be. These are present in lustful people who did not fulfill their sexual desires and lost control of the sacral chakra. It can also be present if the sacral chakra was imbalance in some way like excessive materialism or if it was removed from their body. Ghosts usually become sacralized by incubi or succubi willingly so they can feed off of them indefinitely and ghosts with this affliction are called sacrals, navels, or navelized. Because the sacral chakra limits creative energies and regulates them, the sacralized ghosts actually have a lot of potential for manifesting if they choose that. It is considered impossible for a sacralized ghost to have holes in their chest because they would be regenerated with the limitless energy that sacralization gives them. You are not likely to encounter sacral ghosts unless you work with incubi, and even that is rare.
