Eating Meat (general)
Scholars have said that if one dreams of eating their own flesh or the flesh of another, and there is a clear impact from the eating, it may indicate consuming from their own wealth or someone else's. If there is no impact, it might suggest backbiting a family member or others. Eating the flesh of the crucified could be interpreted as consuming illicit wealth from a high-ranking person, provided there is a clear impact from the eating.
