The Koan of Recursive Dreams

PROC recursive dreams = VOID:
BEGIN
# In dreams we dream of dreams #
REF VOID consciousness := NIL;
IF consciousness :=: NIL
THEN recursive dreams
ELSE SKIP # who dreams? #
FI
END

Uses the koan form to present a paradox through code. The recursive structure mirrors the cyclical nature of consciousness, while the comment acts as a traditional koan statement. The final question 'who dreams?' serves as the koan's turning point.

Employs ALGOL 68's procedure recursion, void return type, and nil checking to create an infinite contemplation. The lack of a base case is intentional, reflecting the endless nature of consciousness.

Explores the Buddhist concept of no-self through recursive dreaming. Questions whether consciousness is recursive in nature, and if so, where does the recursion end? The nil check represents the boundary between consciousness and void, while the final question challenges the existence of a discrete dreamer.
