The significance of lipupudsu among the Dusuns of North Borneo

A lipupudsu would look like a hardened soil or clay and they are seen to exist in several locations near village house premises. When I was a boy, I used to sit on a lipupudsu that existed very close to the ladder of our house in the village. A witcher used to tell me (us, the children) that a lipupudsu was formerly a tomb and so it shouldn't be demolished. If it was demolished the dead rotten body would be seen and that would be a very bad sight that would invite fear in the person who has seen it. My superstitious ancestors never knew that a lipupudsu was termites' architecture. A more fearful story ever told to me about the lipupudsu was that it was a sitting place of a nocturnal human-eating wolf. The wolf would produce a weird sound at night and if its sound was heard by the witcher (usually a woman), she would immediately caution everyone in the house not to lie to sleep on their back but should immediately turn to their side or chest. If anyone failed to obey, the wolf would come into the house and step on the chest of the person until the person die. When the person died, the wolf would take out the person's heart and eat it. I would think that without the lipupudsu the wolf might not have a resting place and so its sound would not be heard by anyone. Everyone should enjoy sleeping at night without fear. But my superstitious ancestors might have become sleepless at nights just because of fearing the sound of the wolf. They couldn't demolish the lipupudsu as well. If they could remove it, they would sleep peacefully at night.
