The recollections of children or adults (adults often through hypnosis) about past lives when the details can be verified should not be dismissed lightly. How can it be overactive imagination when details can be proven? The odds against that are enormous. Does the child hear about a past experience and then imaginatively elaborate on those details, thus creating a false memory? Possibly, in some cases, but there are too many cases for that to happen in every case. Do parents influence children to tell tall tales and call them memories for financial gain? That can happen, too, but in many cases the exact opposite is true: people don't want to talk about the experiences for fear of ridicule. I don't know that reincarnation can ever be proven in a strictly scientific sense, because reports about it rely too much on subjective experience and/or interaction between a hypnotherapirst and client. Double blind studies, objectivity, and reproducibility are the hallmarks of good science, and the study of reincarnation seems to be resistant to all of those methodologies. But something seems to be happening, and it needs to be explored further.
