Are you having interactions?
Insightful
Since your interaction would be from a different perspective, the insight gained would likely be varied and different. You might also draw quite different conclusions.
Accurate
As accurate as you (or they) could interpret and record it. Ultimately it's not very accurate at all, as it loses something in the medium (as does this form of communication). The light goes on when you recognise something of another's experience that is akin to your own - as we have all experienced on this forum regarding the JW's, even if we can't always follow the precise experiences of some.
Valid
It's validity surely stems from the accuracy of interpretation and recording. I don't know exactly what those individuals experienced, but it does validate much of my own experience ex-post-facto. I'm talking here in a biographical sense of "God".
