To address the OP:
Subjective reality is precisely what exists here.
Pimply adolescents posing as intellectuals, when the only things they 'know' are things they themselves have never experienced.
Hence the endless quotes from other people.
This is so, they say, because I read it, here, and here...
Which is about as far removed from knowledge as it's possible to get.
A parrot does something very similar, but is far less pompous about it.
Yet anyone with actual experience is derided, for not being able to 'prove' his experiences.
Evidence, proof, substantiation, sources, etc...
Anybody who actually experiences life is too busy experiencing it to be concerned with proving it to anal-retentive sceptics.
Maybe you all prefer to inhabit a virtual world where nobody ever experiences anything, and nobody is able to discuss anything.
May it nourish your ravenous egos. May it bring you joy.
And that is subjective reality.
You can keep it.
