That's another word for saying "supernatural"...or "imaginary"...or "mythological"...or "delusional"...
...do I really know to go on?
More of the same, above.
Except that I might add, that the whole "absolute" business that some religions talk about, are sham, just like that of theism. It is still faith-based belief, and nothing more.
This "reality" you talk of, the other reality, is no different to people who go high, with ecstasy, whether that be drug or non-drug ecstasy. But to me, it is nothing more than delusional belief.
