An answer compatible with Christian theology can be found following the attempts of psychiatry to find an equivalence between evoking "personalities from past lives", by the use of hypnosis, and the multiple personality phenomenon. As was previously mentioned, there remains an unexplained element in the attempt to understand both phenomena on a purely naturalistic basis: How are the personalities distributed in their roles, or who decides which one is to act next in the show? It cannot be a random process. Using the words of Ian Wilson, "the show must have a ‘director’".

Parapsychologists tend to attribute the "director’s" role to some personal external entities, which act through the process of channeling. Hypnosis generates perfect conditions for contacting these entities as a result of abolishing normal consciousness. Instead of presenting their true identity, they could introduce themselves as personalities evoked from previous lives. Until now enough cases of external spirit interference in producing reincarnation stories have been discovered. Most people are not aware of these undesirable parasitic attachments while recollecting alleged past lives stories. Those who are aware of them accept them as precious aids in the recollection process. The only reason for rejecting the hypothesis that past life recall stories are pure fiction invented by these entities is the sheer belief in their honesty.

Now if we pass from the realm of parapsychology to Christian teaching, it appears obvious that such "external personal entities" exist, and have sufficient reason to lie us about spiritual reality. They are called demons and have developed most ingenious techniques to fool mankind about spiritual reality. The Apostle Paul states:

And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve (2 Corinthians 11,14-15).

If we accept Biblical revelation, admitting that demons exist and do their best to fool us about spiritual reality, why not accept their possible involvement in producing reincarnation proofs, a concept that blatantly contradicts the essence of Christianity but at the same time fits well with their purpose? If the best conditions are created to express themselves through the person undergoing hypnosis (when self-consciousness is abolished), why should they not act? Why should they not respond to the invitation to fulfill their purpose in such a fascinating way for a credulous and ignorant public?

The experience of spirit possession represents full or partial takeover of a human by an external spiritual entity (a demon). This phenomenon is known to most religions. The parasite spirit exerts control over the behavior, mental functioning and emotions of the person involved, being capable of producing sensations and symptoms in the physical body. This picture is obviously very close to what is happening during hypnotic regression. Why then reject its explanation as spirit possession and believe in past life recall? As to the information they produce from alleged previous lives in the form of historical accounts that correspond to some extent with reality (but always are most suited to win people’s trust), if humans know them, how much more are they available for demons? If humans are capable of creating historical scenarios using the facts they know, how much more could demons prove equally creative?

In the case of "spontaneous past life recall" by children, the mechanism could be similar. At the age when they recall the alleged past lives (generally between two and five years of age) their spiritual discernment is not formed yet, which makes them vulnerable to demon manipulation. In a previous section on this phenomenon we have seen that there are cases when the alleged soul’s reincarnation overlaps with the personality of the child, presenting typical symptoms of demonic possession.

In conclusion, there is no possible way to reconcile Christianity and reincarnation. As Ian Stevenson, a well-known researcher of past life recall experiences, concluded in his book Twenty Cases Suggestive of Reincarnation that they are only "suggesting" reincarnation and not "proving" it. From a Christian perspective however, they rather suggest demon possession and therefore should not be used as a method of getting information on spiritual reality.
