/lit/ - Literature

Books about reality literally being an illusion, a play, or something similar?
I don't mean pop sci simulation theory shit.
It's often assumed (for good reason, obviously) that this existence is meaningful and that your actions in this life significantly influence what happens in the next, instead of existence as we perceive it being unreal and inconsequential while still believing in some form of afterlife.
I lean towards the latter and I'd like to know if this has been addressed by any thinkers.
