I like the moon when it is huge and looks like it is so close to land.
The moon is an important part of your chart(some books say more important than your sun sign). Your sun sign is your outer personality, while your moon sign is your inner, what you really are thinking/like.
I've definitely heard this as well. Especially when reading about my scorpio moon...I've read that a moon in this position can easily overpower one's sun sign because of the power and intensity of scorpio. I'm sure with my sun being in pisces (passive, receptive), this is even moreso true. Many people who are into astrology think I'm a scorpion upon meeting me.
