That was written on the metal plate engraved on the door of the cabin, where Luna was being admitted.
It's been 3 long days since she hasn't woken up from her deep sleep. After she got shot by coming in between the bullets to save Alex from the attack, she suffered from profound blood loss.
Due to profuse bleeding doctors had to undergo a massive surgery to operate out the bullet that passed through inside her waist. However, her body went into a state of shock while facing such a traumatic experience. That's the sole behind her loss of consciousness in these past 3 days.
