I;m not the guy you responded to. I actually agree with you.
The story is a good story with likely no basis in reality. However, there is, I do think, a connection between people, plants, animals, and subatomic matter. After all, it's all made of the same stuff. I think there's a single root consciousness, and each person is a deviation from the same quality due to circumstance.
For instance, we all become different over time .We at every point in time exist in some way. Most of the time it's matter. Sometimes it's as brains. It comes from sperm inside a male, which came from the womb of a female, ad absurdum, until you return to the same source.
Our source is likely matter slowly forming together. We are all materials in a particularly alike state.
Therefore we all would act and think and feel the same way, IF we we're in the same situation as someone else. You'd have to be in the EXACT situation, with their thoughts and feelings and past and body.
