A burial place indicates the digestive and elimination system. This is regardless of whether the burial place is for an animal, pet or human. The color brown (see colors) and the earthiness of the burial place are sufficient to indicate the digestive system. Any dream where digging into the earth / dirt is involved implies the dirt track of your body, which is your colon. However, a morbid symbolic link exists because both the digestive system and a burial place are used to receive dead meat.
