I believe this happened and you did experience it but I don’t think we know or have insight into the perception or an understanding/explanation. My guess, not a popular one, is that you were accessing (metaphorically) a different part of what is an enormous “database”. If this (what we are experiencing as “life”) were a simulation we would expect some of us to get occasional access into other parts of the operating model, it would be slight glitch in a particular avatar configuration. It would not be surprising if those who did have these experiences learned how to approximately access the places in their system that allow the insight.
