thats a bit deep for me to think about at the moment, although the light reflected by the moon is negative energy, i believe, hence cold., and that from the sun positive, hence warm. i still believe it to be radiant energy, the sun and not have dwelled on the moons energy,, but i expect it to be similar in a negative way. as far as the moon being a source of energy, i think not, just reflective.
as far as sleeping under a full moon, the term lunacy comes to mind. as far as falling asleep under the full sun, now thats just retarded.
