Room 304: Never existed

Every night at exactly 3:04 AM, Vihana hears three knocks outside her hostel room.
Slow. Heavy. Unnatural.
The sound always comes from Room 304.
But according to the college records, the third floor only has 303 rooms.
At first, Vihana tries to ignore it.
Until she begins finding wet footprints in empty corridors, burnt photographs hidden inside walls, and diary pages written by a girl named Meera - a student who supposedly died in a hostel fire years ago.
As the mystery deepens, Vihana realizes someone inside the hostel is hiding the truth.
Students are lying.
Records are disappearing.
And the closer she gets to Room 304, the more fragmented her own memories become.
Because the hostel isn't haunted by a ghost.
It's haunted by what really happened that night.
And some doors were never meant to be opened.
