I was in a familiar place, suddenly flood rushes from downwards.
Dreams of floods often symbolize overwhelming emotions or a sense of being out of control in certain areas of your life. Since you were in a familiar place, it could suggest that these emotions are related to something happening in your waking life that you are accustomed to. The rushing floodwaters may indicate that these emotions are coming on suddenly and forcefully, potentially catching you off guard. This dream may be a reflection of feelings of being overwhelmed or inundated by a particular situation or set of emotions. It may be helpful to identify what in your waking life is causing these intense feelings and work towards addressing them in a positive and constructive way.
