I dreamed of the moon suddenly turning Blood Red what does this mean?

maybe the moon was telling you about it's day, and what it saw. Maybe those colors are the pattern of sky colors it saw while the day went by. It's always there, we just see it best when the sun's light reflects off of it onto the earth. maybe it was saying it saw the sunrise, then the day went by so fast it seemed that it instantly turned to night, when it's black out.
