In most cases, you see what you want to see or are capable of discerning.

So reality can be structurally different between different people?

I think so.  It's the nature of Maya, separation.  We're all little baby Creators creating our own separate realities.

Basically, we contextualize data into the narratives which we accept as defining our reality.  So, if we expect an ET to look this way or that, we tend to accept or reject what we see, or what someone describes, according to how it conforms with our narrative. 

You see it on these forums everyday.  Someone makes a comment and the next person pulls it out of the previous person's context and puts it in the context of their own narrative--exactly the way I am doing now, and exactly as someone will do to this comment soon enough--and most people end up talking right past one another because they cannot bridge the differences in contextualization or, to borrow your terms, their structures of reality.

And so it goes in the land of the primary energy centers where true convergence or blending of energies does not compute, for the most part.  It's pretty darned exhausting, if you ask me!
