This refers to when the subject behaves adequately in terms of communication and interaction, but nevertheless shows no sign that he ever knew the practitioner. Meanwhile, this person may be exactly the same as the practitioner is used to seeing him, with the same character traits and physique. He may know his name, but everything else, especially the life history he describes, may not have anything to do with reality.
It is safe to assume that this lack of a true-to-life memory in a deceased person will present no obstacle to communication for some practitioners. Lack of true-to-life recall in a deceased subject is truly not all that important when compared to the joy of finally seeing a loved one again. A practitioner reunited with a loved one would hardly think that their encounter were unsuccessful if the deceased acted like a stranger, and would hardly see it necessary to take corrective action, as this type of communication allows the practitioner to once again see those same eyes, hear that same voice, and so on.
Perhaps those encountered do not need to remember what happened to them or know where they are? Maybe it’s best to let them live in their reverie, seeing the whole situation in a completely different light? Does one really need to go through all of the ordeals that may arise after they realize their situation? That’s why, before implementing measures to achieve more true-to-life contact, one ought think long and hard about the wisdom of doing so.
One should interact as naturally as possible with a person lacking memory of the past, as this is just what the situation calls for. It should be kept in mind that brining up what happened in the past might evoke negative reactions in the subject, which is why sometimes it makes sense to introduce oneself to him and talk to him as if for the first time.
