Physics Experiment Challenges Objective Reality

I'm fascinated by recent news of exciting results from a quantum physics experiment that according to the MIT Technology Review appears to provide evidence that two people can observe the exact same event, see two different things happen, and both be correct.

Observers Witness the Same Event Differently

Physicists at Heriot-Watt University in Edinburgh succeeded in bringing a classic Gedankenexperiment (thought experiment) out of the realm of pure conjecture and into the real, physical world of a physics laboratory.  The thought experiment requires two people to observe one single photon--which is a quantum, or indivisible, unit of light.  Quantum particles can behave as either particles, or as waves, settling into one state or the other (particle or wave) at the precise moment it is observed.  All the rest of the time when the particle is not being observed by someone, it exists in a 'superposition of states' in which it can be considered to be simultaneously both 'particle' and 'wave.'  When a second person is unaware of the first person's observational measurement, this thought experiment proposes that the second person who is unaware of the first person's measurement might be able to to confirm that the photon still exists in a quantum superposition (undecided) state.

I clocked an odd one a couple of months ago regarding Bob Marley; I had always thought he died of cancer starting at the big toe; and on impulse checked and was surprised to find he had died of gunshot wounds in an attack (an attack I had never known of). After that, I was going to comment on this, and checked again a couple of months later, and found an article about a CIA man claiming to have induced the cancer that caused his death. I m going to check now lol.

I have had some visions of upcoming lifetimes of living different versions of my life, such as different careers, spouses, education, and outcomes with longer lifespans and more time in life stages, absence of heart attacks and strokes, and more time with relatives currently deceased. But I have also had visions of other lifelines exploring fantasy worlds like middle earth, narnia, the wizarding world, or other places such as the Elysian Fields, the new Jerusalem of revelation, places of myth, and happy hunting grounds or other cultures versions of the afterlife. Is this all normal?
