I'm not exactly sure as it could be various things. It might be a story about the relationship between 'hum' (us), 'tum' (you) and a ghost. Maybe it's a spooky adventure where 'hum' and 'tum' encounter a ghost and have to deal with some strange situations.
The title 'hum tum aur ghost story' gives a hint that the main characters are likely to be the ones referred to as 'hum' and 'tum'. 'Hum' could be the narrator or a group of people involved in the story. 'Tum' might be another person related to 'hum', like a friend or a partner. And then there's the ghost, which is an essential character as it's part of the 'ghost story'. The interactions between these three elements - 'hum', 'tum' and the ghost - would probably form the core of the story.
I'm not entirely sure about a specific 'hijack' full story within 'Diya Aur Baati Hum'. It could be a fan - made or a very specific plot point that might not be widely known. Maybe it was a situation where a character was in a vehicle that got hijacked during a particular mission or journey in the story.
