its good to know that even being a parapsychologist or shaman ona has certain limitations and certain dangers. After all this is working with souls or demons:
Imagine observing a medical operation that goes wrong: could you recognize what went wrong even if looking at all available displays or listening to short words spoken between the operating crew? Might be difficult...
Imagine yourself being able to see with your own eyes (even only as a vision) what was happening inside the cabin during the long minutes when the plane was falling down and when it started to sink. Could you mind stand up to the memories of witnessing sounds and pictures of people starting to understand tey are doomed? Memory of this would stay with you forever, every night and day.

Just think how many people use similar technology when digging for water.
