Kafkaesque
It can also describe an intentional distortion of reality by powerful but anonymous bureaucrats. "Lack of evidence is treated as a pesky inconvenience, to be circumvented by such Kafkaesque means as depositing unproven allegations into sealed files ..." Another definition would be an existentialist state of ever-elusive freedom while existing under unmitigatable control.
The adjective refers to anything suggestive of Kafka, especially his nightmarish type of narration, in which characters lack a clear course of action, the ability to see beyond immediate events, and the possibility of escape.
