Another concept to boggle your mind with and to mull over........
The 'block universe' theory suggests that the past, present and future does not flow, but they exist simultaneously. We also know that children tend to have much better sensory perception than adults, which generally gets lost with age.
Most reincarnation cases in children occur between the ages of 2 and 7. Coincidentally, this later age is around the age in which our 'sixth sense', in the majority of cases, starts to 'dull' over.
As opposed to actually being 'possessed' (I use the term very loosely) by a living soul who has passed over, what if these children have the capability to actually tap into the 'past' as defined within the 'block universe' theory? Slightly diverging, what if this is also true for a prophesier/ fortune teller/ doomsayer - someone who can tap into the 'future' within the 'block universe' theory and predict things that will happen?
If the past, present and future do really co-exist in the here and now, is this not a logical possibility?
