In the limitless expanse of the shared dream, a shadow flickered. It was a thought, a possibility, that had never before existed in their shared consciousness: the idea of an end. With this thought came a new feeling, a cold tremor that ran through the dreamscape. It was fear. The fear of non-existence, of the beautiful, intricate dream dissolving into nothingness. This fear was not a monster to be fought, but a presence to be understood, a new color in the palette of their shared reality.
