There is nothing mysterious about knowing you are in a physical illusion since you planned exactly to be in one pre-incarnation. You, and I, purposefully chose this path. Without this understanding, the physical illusion becomes intolerably confusing.
We have a particularly stagnant community here, headlocked into chasing shaky videos and 'seeking ET' when the answers can be found by, uh, asking ET. There are dozens of ET channelers some of whom have been addressing ET issues for decades but you will find those information sources poorly represented on this forum. IOW, the chase has become more entertaining than the truth.
I have no idea what you might consider as evidence or not. My personal experiences with OBEs, entheogens, physical mediumship (the study of and the participation in) and, again, following the instruction and information paths of ET channelers (another more modern form of [independent] direct voice physical mediumship). They are very clear as to how the multiverse works, the mechanics of it and how we create our own physical illusion for the benefit of that learning experience.
We create the illusion by our consciousness shifting between, guess what?,
parallel realities gazillions of times per second. From this shifting we get the illusion of space and the illusion we call time. Shifting parallel realities is akin to a film running still frames 24x/sec, or video changing still-pictures 25 or 30 times per second. It happens so fast, that it creates the illusion of smooth continuous motion.
