To dream is ok. The Thought Police of today allows it.
Lucid dreaming, on the other hand, is a crime. Their dreams bring about wild ideas of an everlasting, unbending spirit that lives in all, breathes life into all and cannot be tamed and traded with.
The solution of the righteous to prove to the aborigini the frailty of their theories is to systematicly wipe them out, so that when there are no more of them, their ideological spirit will have to transfer onto a stone, which will be turned into a house, or into a white man, who will work under Nation and God. A win-win situation.
