What is your understanding of 'reality'? Alexander Dugin has a wonderful lecture completely devoted to "reality", he considers reality not as something material or metaphysical, but as a kind of human concept, a contract. There is no reality in the concept of "real". this is an absolutely redundant concept.
At the very beginning of the novel "Journey to the End of the Night"
Louis Ferdinand Celina has the following lines - "travel is useful, it makes the imagination work"
Man does not travel through reality, man imagines
the person gives the installation that he lives in the "real world".
This is one of, in my opinion, although not a lot of radical, but an applied position, although this question is 100% dependent on how you understand reality, but if you take reality as such, then this is tantamount to talking about truth, the meaning of life and other eternal questions
