The King Decapitating Subjects
Scholars have said that seeing a king decapitating his subjects might indicate his forgiveness of wrongdoers and their liberation. For a slave, it suggests freedom or sale, and for capitalists, it might signify the loss of their capital. For travelers, this dream means their safe return.
