This dream may symbolize a desire for reconnection with someone from your past. The sudden awakening in Eva’s room could represent a sudden realization or reminder of this desire. The fact that you were under the bed may suggest feelings of hiding or avoidance in regards to this person. However, your eventual emergence and greeting of Eva could indicate a willingness to confront these feelings. Eva’s request for quietness to avoid her mother’s suspicion may represent a fear of judgment or disapproval from others in regards to this reconnection. The transformation of the bed into a bath and the playful drowning may symbolize a cleansing or release of these fears and anxieties. Overall, this dream may be a reflection of your subconscious longing for a reunion with someone from your past, and a reminder to confront any fears or hesitations that may be holding you back.
