In 'Nightmare Exchange', players find themselves in a surreal realm where insomnia-prone insomniacs barter their nightmares for fleeting moments of joy. You awaken in a dreamlike bazaar, where the trade is not just limited to terrifying experiences, but also the emotions tied to them. As you navigate through strange stalls and bizarre characters, you must gather insights, confront your fears, and selectively exchange nightmares with other dreamers. Each exchange powers up your abilities to face the ultimate challenge: confronting the dream custodian, a sinister entity bent on harvesting your fears for its own gain. The narrative changes based on your choices, making each playthrough a unique exploration of psychology and self-awareness.
