As discussed earlier, philosophical ideas about reality based on real experiences, can counter the influence of scientism.
But the problem is Sriram that people who have the same experience may interpret them completely differently and hang them on highly distinct philosophical ideas which will typically be based on the philosophical 'mood music' of their cultural and societal upbringing and environment.
So all we get is a mire of subjectivity with societal and cultural overlay. None of this takes us anywhere useful in terms of actually understanding of the world rather than investigation of societal norms which may, or may not, align with any actual objective reality.
We can, of course, learn from experiential evidence, but to do so requires robust scientific method that first unpicks reported experience that cuts through cultural mood music and overlays with sound objective science.
So on so-called near death experiences (they are nothing of the sort as plenty aren't associated with near death). Use your approach and they tell you about death, and they tell you that individuals are watching the journey to heaven, or other people that they are watching their reincarnation, or others still that they are just witnessing death. Now even though the experience may be both real and consistent, none of those 'philosophical ideas based on real experiences' have any evidence to support them.
Overlay solid science and we can understand the changes in physiology that are associated with these experiences, and demonstrate them to be causally associated with oxygen depletion. Further these experiences can readily be replicated in circumstances where there is temporary oxygen depletion but have nothing to do with death. It may, of course, be that this type of oxygen depletion occurs near to death and probably both in people who actually die and those who recover. But the phenomenon isn't necessarily associated with death and has a physiological, not a philosophical explanation.
