The concept of a Walk-In is somewhat similar to Starseeds. A Walk-in is a person whose original soul has departed his or her body and been replaced with a new soul.

This soul exchange takes place voluntarily for many reasons, usually when the original soul is experiencing physical, mental or emotional difficulty with it’s current life incarnation and wishes to depart without physical death.

In order to do so, another soul must volunteer to come in and exchange places with the host soul. The walk in theory should not be confused with “possession”

The contract of exchange between the host soul wishing to depart and the soul willing to walk-in takes places on a spiritual/cosmic level. The actual exchange commonly takes place during a traumatic event or accident in the original souls’ life, or during an unconscious state of mind.

Once the walk-in occurs the new soul becomes “the conscious blueprint” of the original, retaining all memories and life experiences as if nothing had ever happened. Like starseeds, the walk-in soul usually originates from a 4D or higher dimensional level, although the 4D is the most common since it’s vibration is closer to the 3D vibration and the “adjustment” can take place more easily.

Once the walk-in soul has become incarnate in the host vehicle (body), the original soul inhabiting the body departs and is brought to a place where it’s life may be reviewed, discussion over the souls decision to leave the earth plane, and guidance may be given regarding the next incarnation.

In the original host body the new walk in soul usually retains no memory that such an event has just taken place, but it is possible for them to recover fragmented memories of their previous existence, or current purpose for incarnating.

The new soul/individual is still the “same person” they were before. There sometimes may be a sudden change of interests or in personality after the walk-in occurs due to the “new vibration” of the host body.
