A caveman is defined as a cave dweller especially of the stone age. Metaphorically, it represents a man who acts in a rough or crude manner.
Positive: Dreaming of a caveman could represent humility. It could represent one who acknowledges the fact that they need the wisdom of God.
Negative: In a dream, seeing someone depicted as a caveman could represent one who is unwise and brutish.
