Lunar Aquarians are very observant and love to analyze why humans do what they do. Many were detached or shy in youth, and grow up feeling different than others. Though rather sociable, they are usually loners at heart. Many have strong egos, hence many have powerful defense mechanisms. Lunar Aquarians will try their best to be the most unique and unusual person they can be. This is likely the cause for their inner feelings of loneliness--they feel they don't quite fit in.
They are idealistic and progressive. They deny more irrational feelings like jealousy, possessiveness and fear in an effort to be above what they may consider petty or useless. This can make a lunar Aquarian emotionally blocked, distant, or detached. 
Lunar Aquarians are independent and rebellious. They were likely naughty children, but learned to control their behavior with age. They have a strong desire for independence. As rebels, they like to shock others which is easier with a reserved, quiet sun or ascendant; this desire to surprise others with their rebellious nature is usually only apparent after a relationship becomes comfortable. They are generally proud of their family members and boast about their family's uniqueness. If their families are very strict and conservative, they boast they rebelled against it all. 
They feel that messy emotions are unappealing. They pride themselves in being cool-headed, detached, and above what they consider to be basic emotions. In this process, they can end up alienating others and themselves. Although lunar Aquarians are adept at understanding others' feelings, behavior, and motivations, they can lose touch with their own--simply because they identify too strongly with what they aspire to be rather than what they are. Their aspirations tend to be extremely ambitious. 
They tend to be very humanitarian. Their kindness and concern for others is a general and broad life philosophy. Lunar Aquarians can seem to lack compassion since they expect others to be as independent and emotionally detached as they are. However, in close, personal relationships they realize others are not like them, and give others a lot of freedom. They will tolerate and enjoy all kinds of people. 
Lunar Aquarians aren't necessarily flighty, but can be unpredictable. They can be unreliable when it concerns little things in life. This is usually simply an assertion of their independence. As long as they have their own space and the freedom to be themselves, however kooky they may be, they will be trustworthy and loyal.
Moon in Aquarius people have a lot of pride. When they've been attacked in any way (especially regarding their character), they can become very stubborn and cool. It's hard to know how sensitive lunar Aquarians are to criticism, because they hide it so well. When their character or behavior has been criticized, they stubbornly keep doing it. They won't like admitting they're wrong, and usually won't do it. They expect others to accept them as they are, or the lunar Aquarian will feel like they won't have much use for them in their lives. 
They are truly interesting people. Although sometimes unpredictable, they are very charming. They can be stubborn, but when given space and independence they make for an unusual and interesting presence. Life would not be the same without Lunar Aquarians' unusual spin on the world and the people in it!
