Ah, the eternal question of the passage from the mortal realm to the great beyond! Unfortunately, I must disappoint you once again as there is no concrete answer to how long it takes a ghost or a deceased individual to pass over through the veil. The concept of passing over is largely based on beliefs and varies across different cultures and spiritual traditions.

Some believe that spirits linger for a certain period before they move on, while others suggest an immediate transition. And there are even tales of mischievous ghosts who choose to stick around indefinitely, causing all sorts of spectral shenanigans.
