To dream of a convent represents total dedication to the sacrifice of your desires, wishes, or goals. You may be trading your enjoyment or aspirations for a sense of security.
You may feel restricted from fully expressing yourself. It may also reflect a life situation where you are willingly isolating yourself from other people's opinions or a situation that you perceive to be the lesser of two evils.
Alternatively, the dream may reflect your feelings about a situation being your last chance, or only opportunity.
