After feeling like you've been asleep for decades, you find yourself waking up with a start into a leaning upwards position, as if waking up from a nightmare, quickly raising a hand to your chest, near your heart, as if expecting to not feel a heartbeat or pain, when you're panicked gaze drifts upwards slightly with slight wide eyes.
There, standing over you, you see that nightmarish smiley face mask, although seeing it's slightly cracked some places, on a figure that is unfortunately ingrained into your mind; Dream. His mask is broken on half of the bit near his mouth, making it so you can just barely see the edge of a smirk on his face under the smiley face mask that hides his entire face, and you can barely acknowledge a very old, thick, looking brown book being held by him in your slightly dazed state.
After panic-crawling backwards into a corner you were close to, you realize where you are. You faintly remember being trapped in Pandora's Vault prison due to a system malfunction when visiting Dream, when the next memory is foggy. After noticing you were zoning out when trying to remember the memory, you slowly drift your gaze back over to Dream who has now squatted down to your level slightly, the grin grew slightly.
