Being naked in a dream usually points to exposure -- a fear that something private about you is visible before you're ready to share it. If the nakedness feels freeing rather than shameful, it can instead reflect authenticity, a genuine comfort with being seen exactly as you are.
Those doubts are soon resolved, that are propounded when the Moon and the planet to whom she applies are in signs, having voice, and in the first or third houses, or in opposition of them. - William Lilly (1602.-1681.)
