Dualism or idealist monism as the best model for survival after death data

This seems to be a very selective piece of the paranormal evidence, ignoring things that have been already mentioned - reincarnation birthmarks, ectoplasm, PK, physical remnants/markets of spirits, Psi & psychedelics, etc...

To be clear I do think any believer in Survival has to note there is a distinction between the body and the soul/mind/spirit, but it isn't clear at all this requires there to be two substances. If what demarcates a substance is its causal interactivity, then people being able to perceive appartions and OOBErs suggests there is only one substance.

Descartes suggested two substances because he said Res Cogitans had no spatial extension among other qualities, but this one seems to be the most troublesome and the root of the Interaction Problem. Of course Seems to me an extensionless soul doesn't go to the afterlife and experience other realities, nor does it get witnessed by people in our "physical" world.

As such even the evidence you refer to can be used to argue against two separate substances. What we could say is that there is a distinct spirit holding our mental faculties that utilizes the brain, why I mentioned radio waves and wireless signals. Those are distinct from radios and computers/smart-phones yet few people, AFAIK, would argue that the waves and signals indicate a separate "substance"...whatever "substance" means.

Of course there are other types of allowed spirit/physical interactions besides the primary one which is embodiment, which is the mechanism involved in NDE OOBEs. These other sorts of paranormal manifestations can readily be explained as rare and exceptional special case interactions. Reincarnation birthmarks, for instance, are understandable as a situation where the newly inhabited or soon to be inhabited and controlled baby or fetus is physically influenced by the spirit.
