The clause, "these men dreaming" (that is, in their dreams), belongs to all the verbs, "defile," "despise," and "speak evil."

Their speaking evil of dignities is because they are dreaming, and know not what they are speaking evil of (Jude 10). "As a man dreaming seems to himself to be seeing and nearing many things, so the natural man's lusts are agitated by joy, distress, fear, and the other passions. But he is a stranger to self-command. Hence, though he bring into play all the powers of reason, he cannot conceive the true liberty which the sons of light, who are awake and in the daylight; enjoy" [BENGEL].
      defile the flesh-- (Jude 7).
      dominion--"lordship."
      dignities--literally, "glories." Earthly and heavenly dignities.
