[Jqan Sand (OP)]

At the time of my experience of being in a parallel time line of this universe I was neither tired nor confused nor lacking any form of awareness, I was fully aware of the details of the familiar path in the park where the experience took place and the differences were substantial. When, in a a matter of about ten minutes, I returned to my normal time line, the differences had obviously vanished and unmistakable. I have no guarantee that my concept of multiple time lines explains my experience, it is merely my suspicion.

Can you go into details about what exactly you experienced?
