Dream interpretation of hazrat ibn sirin (may allah have mercy on him) said that a torture device in a dream is an indication of humiliation and humility. and if he sees in a dream that he has been caused pain by the device, then the first interpretation applies. and if he sees that he does not suffer pain from the device, then the interpretation is contrary to the first. and if he sees that the king has stretched him on the device, it is an indication that he will suffer from the king.
