Often when I am meditating, I have this vision of full moon just over my head, sometimes hazy, sometimes quite bright. I understand the importance of observation.. but have tickling curiosity to find out if this means anything.
What you're describing could be any number of possible phenomena one could experience while meditating, would you mind telling us a bit more about what sort of practice you're doing?
As far as what it "means", it's genuinely not important.
