A sanctuary in a dream is a place where you keep your secrets.
To claim sanctuary in a dream suggests that you have a fear of exposure among your peers. You may be hiding from something on the outside. Try to determine what it is you are escaping from, and confront that problem in your waking life.
In a dream, a sanctuary represents marriage to a righteous woman. (Also see Hermitage; Retreat; Temple)
Dreams of a sanctuary represent your inner calm and peacefulness, and that your connection with your spirit provides you with sanctuary wherever you are no matter who you are with. See Church.
