The "worlds" in the many worlds theory is then just the complete measurement history up until and during the measurement in question, where splitting happens. These "worlds" each describe a different state of the universal wave function and cannot communicate. There is no collapse of the wavefunction into one state or another, but rather you just find yourself in the world leading up to what measurement you have made and are unaware of the other possibilities that are equally real.

The purpose of this interpretation is to overcome the fundamentally strange concept of observers being in a superposition with themselves.

When an observer measures a quantum system and becomes entangled with it, it now constitutes a larger quantum system. In regards to each possibility within the wave function, a mental state of the brain corresponds. And ultimately, only one mind is experienced, leading the others to branch off and become inaccessible, albeit real.^[7]^ In this way, every sentient being is attributed with an infinity of minds, whose prevalence correspond to the amplitude of the wavefunction. As an observer checks a measurement, the probability of realizing a specific measurement directly correlates to the number of minds they have where they see that measurement. 

When two people look at two different detectors that scan entangled particles, both observers will enter an indefinite state, as with one observer. These results need not agree -- the second observer's mind does not have to have results that correlate with the first's. When one observer tells the results to the second observer, their two minds cannot communicate and thus will only interact with the other's body, which is still indefinite. When the second observer responds, its body will respond with whatever result agrees with the first observer's mind. This means that both observer's minds will be in a state of the wavefunction that always get the expected results, but individually their results could be different.

Since conscious awareness has to be coupled with local physical systems, the observer's physical environment has to interact and can influence the brain. The brain itself must have some physico-chemical processes that affect the states of awareness. If these neural processes can be described and analyzed then some experiments could potentially be created to test whether affecting neural processes can have an effect on a quantum system. Speculation about the details of this awareness-local physical system coupling on a purely theoretical basis could occur, however experimentally searching for them through neurological and psychological studies would be ideal.
