Reality is simply experience, a human being is a being who experiences the ''world''. Now in my opinion, everything that is experienced is real, no matter what it is as long as it is experienced it's real. Which means reality is multi-dimensional, multi-subjective, but it's all true - reality cannot be put into a box, nor is it right to deny someone's experience of reality and accept another one's. Who decides what reality is, and who can objectify it? Only fools. That's being, it's One but reality is not just ONE. Take a pill and your whole reality changes, smoke weed for over a year and do spiritual practice like me and you will be labeled psychotic after having the ultimate spiritual breakthrough. Why? Because that's the west for you, that's their logic here in these institutions.
Anyhow, most have an ordinary experience of reality, but isn't that reality too? And a person with psychosis or schizophrenia may experience reality slightly or a lot more different, but isn't that reality as well, isn't his experience his experience of reality valid, just like anyone else? Reality is multi-dimensional, there is no way it can be put in a box, no way.
