Purple Ribcage in dreams
The bones around the lungs and heart — the structural cage that protects what cannot be replaced.
How purple changes the reading
Purple colour places the symbol between hot and cool — a reading that has both calm and intensity at once. The dream often uses purple for symbols that do not fit the usual categories cleanly. Take the reading more seriously than you would otherwise; the colour is asking you to.
The base reading of Ribcage
A ribcage in a dream is the dream's image of the cage around the soft, irreplaceable organs. Ribs do not perform; they protect. The dream brings the ribcage when the question of how well your interior life is currently being protected is alive — by good boundaries, by trustworthy people, by your own habits. An intact ribcage is the dream telling you the protection is in place and the soft organs are safe. A broken or opened ribcage is the dream noting that the structure that was meant to protect your interior life has been compromised, and what should not be exposed now is.
