The narrative deliberately blurs what is real and what is imagined, letting fantasy intrude into everyday life. Barlam's obsession with hidden truths makes events feel dreamlike and dangerous, and the mother figure surfaces as either memory or mechanism of the house, challenging the reliability of everything the characters say and do.
