In 'Nightmare Exchange', players navigate a surreal marketplace where individuals barter their dreams and nightmares for fears and desires. As a newcomer, you've traded away your nightmares, only to discover that your headspace is a battleground for other people's dark dreams. Each interaction reveals deeper layers of your psyche, forcing you to confront your own haunting memories while juggling bizarre dream transactions. The choices you make will alter the fabric of your subconscious and determine if you can reclaim your identity, escape the market, or choose to embrace the chaos within.
