Dead Navel in dreams
The scar left by the umbilical cord — the literal mark of the first attachment.
How dead changes the reading
Dead in the dream means the symbol's energy is no longer in active circulation in your life. The reading is not necessarily grim — most often it is the dream noting that something you had been carrying has run its full course and you can stop carrying it.
The base reading of Navel
A navel in a dream is the dream's image of the literal scar of the first attachment. Every body carries the mark of where it was once connected to the body that made it; the dream brings the navel when something in your life is returning you to the question of where you originally came from. A navel observed neutrally is the dream telling you the origin is acknowledged and at rest. A navel that hurts in the dream is the dream noting that the original attachment is sore — that something from the earliest part of your story is back in the room and asking for attention.
