Walk-ins

[Mystic Wanderer]

It would help decide whether to give a 'yea' or 'nay' if provided with further clarification on 'what' you are calling/counting a 'walk in'.
My experience, that could (possibly) fit into said category is/was extensive, exuberant, and ultimately maddening.
So - Please, if you don't mind, drop a few more crumbs...
Thanks

The walk-in experience I had comes from a very unreliable source, which means it could be more imagination than truth, though it had the visceral effect that makes me leaning more towards truth, than I feel comfortable with.

I have not yet learned the origin or the source but I was told that they first tried to enter animals with very poor results.

I am led to believe that there are more than one type of walk-in, or should I say, they don't all share the same level of ability. Some can make the transition seamlessly, while others are so awkward that they draw attention to themselves right away. They are often mistakenly diagnosed as being ill.

It was shared with me that more are learning the ability, but the majority still are not skilled enough to go unnoticeable.

I left out some details to see if anyone else has heard of this phenomena and if they can fill in some of the blanks.

As I understand it, a walk-in is a disembodied spirit that possesses a living human body. It can do this while the spirit of the living person is still "in there". 
Sometimes they may just want to use the body for a short while to get a message to loved ones; other times they want to take over completely. This is when it becomes a battle for which spirit is strongest. Sometimes an agreement is made between the two to allow equal time using the body. This is what doctors call a split personality.

I do have some stories on walk-ins somewhere, but I don't know if they're here, or on ATS.  I'll try to do a search later.
