Recurring dreams about discovering secret rooms in a house often represent a journey of self-discovery or exploration of your inner thoughts and feelings. Houses in dreams typically symbolize the self, and each room can represent different aspects of your personality or experiences.

Finding secret rooms may indicate that there are hidden parts of yourself or untapped potential that you are beginning to uncover. It could suggest that you are going through a phase of personal growth or transformation, where you are becoming more aware of your strengths, desires, or even unresolved issues.

Since you mentioned that you haven't had this dream for a while, it might imply that you’ve made progress in exploring these hidden aspects of yourself, or perhaps you have reached a point where you feel more comfortable with who you are.

Consider reflecting on what these rooms might represent for you. Are there areas in your life where you feel you could explore further or aspects of yourself that you have yet to acknowledge? This dream could be an encouraging reminder to continue your journey of self-exploration.
