Briar,
The primary symbolism of the moon is one of mystery and the feminine. If the moon is full then it could represent completion. It is also symbolic of new beginnings as well as fertility. So there are several possibilities to your moon. I think the most logical would be the feminine aspects. As an aspect of the feminine it could suggest there is something within you that has yet to be fulfilled or discovered.
Let's look at the other symbols in your dreams and see if they provide other clues. Give these some thought and see where they might fit in your life.
First dream:
Bedroom - Many look at the bedroom as having associations with sex and that could have applications. But it may symbolize a need to contact those inner feelings and emotions that will lead to a better understanding of who you really are.
Window - A window is something you look through and gain insights to your inner self. In your dream you are looking out the window and that may indicate looking for something 'outside' that will provide wholeness {moon} in your life.
Sky - A symbol of transcendence, expression your true self, especially a blue sky as in your dream. You enter into the unconscious realm when you have dreams of celestial symbols. That may suggest unconscious desires, something you wish for that will transcend your life to a higher existence.
So in this dream you have something to do with the feminine, possibly to do with sex as well as getting in touch with your inner feelings, something that would be beneficial in your waking life {outside} and would provide true expression of who you are transcending something that may be holding you back from that true person.
The next dream you were not sure if it were a dream. What in your life would fulfill your life, something real and not a dream?
Then there is the dream involving your husband. This dream may be important. What is it that you believe would be so beautiful but you can not 'get him up' to it? Something he should see as being beautiful also?
What is it in your life that would real comfort, make you whole and complete your life? Answer this question and you will probably solve the answers to your dreams.
One possibility that comes to mind. Only one possibility but one to consider if it fits. Do you want children? The moon is a symbol for new beginnings. One dream involves your husband. Could this be the answer?
Other than that look at what I have given and see what fits with your life.
