There is no good in seeing it in a dream, because of the lives that depart in it, the stripping of hides from bodies, the shedding of blood and the foul smell. Seeing it may indicate the fulfilling of needs, joys and pleasures, because it is a help toward them. If a sick person enters it, he will die and his heirs will divide his estate and his belongings. If a healthy person is soiled with some of its filth, it indicates trouble, illness or debt. If he sees pigs, or what is unlawful to eat, being slaughtered in it, it indicates the destruction of wrongdoers and innovators, and if people fear an enemy they will be victorious over it. The slaughterhouse is a house of torment, injustice and imprisonment: whoever enters a slaughterhouse should beware of prison or of being brought before the police. The slaughterhouse is a procuress, because of the blood, the dung and the vile smell in it.
