Well, without more information, it's difficult to say precisely. But generally, a 'dal night novel' could potentially be a work of fiction that uses the night in a place called Dal as a backdrop. It could explore themes like the hidden side of the town or the different personalities that emerge after sunset. There could be elements of suspense if it involves things that only happen at night, like a secret society that meets during the dark hours or strange occurrences that disrupt the normal night - time routine in Dal.
I'm not entirely sure as it could be various things. It might be a visual novel that has some sort of recurring or 'dal segno' (from the sign in music notation which means to repeat from a certain point) element in its story or gameplay.
I'm not aware of any specifically popular 'dal segno visual novel' titles off - hand. It might be a relatively niche concept within the visual novel world.

Well, one possible scary story could be about a tragic event that occurred in the past in Sycamore Park District. Maybe there was an accident where someone died, and now there are rumors of their spirit lingering. Another could be related to an old abandoned structure in the district. People might say that if you go near it at night, you can hear screams or feel a strange coldness. There could also be stories about strange animals that are seen in the park that seem otherworldly, like a large black dog with glowing eyes that vanishes when you approach it.
