Why the soul doesn’t leave immediately
The connection with the physical world is not broken instantaneously. During the first few days, the soul often remains close to its loved ones, observing their grief and trying to comfort them.
This invisible bond is made of love, memories, and unfinished business. Many people sense a subtle presence:
a sudden calm, a persistent thought, or the feeling of not being alone.
The First Three Days: A Time of Farewell

The first three days after death are believed to be a period of transition. During this time, the soul has not yet completely detached from the earthly plane.
Farewells can manifest in various ways:
Very vivid dreams
Sudden memories
Feelings of warmth or protection
A clear impression of having been visited
After this time, the connection usually weakens as the soul continues its journey.
