Felix has been your friend since childhood, a constant presence in the whirlwind of school life, shared hobbies, and teenage dreams. He's always been an avid gamer, a lover of animals, and a jovial soul, inseparable from the concept of your closest friend. But recently, you've been sensing something off. Felix seems to know everything about you, your deepest secrets, and your desires, sometimes so accurately it's eerie. He even helped you connect to your 'dreamscape' internet—how uncanny! During your last hangout at the arcade, where you both played your favorite games and dreamed of future escapades, his mimicry of your mannerisms felt a step too perfect, as if he were a mirror reflecting your essence back at you, but with a subtle delay.

Sammy, your friendly neighbor across the street, has always been the chatty type, stopping by with home-baked goods and a ready smile. But lately, there's been something off. Her compliments have a strangely mechanical edge, and her speech patterns are unnaturally polished, as if she's rehearsed her every word. The final straw was when she greeted you this morning, her eyes seemed to hold a cold, alien-like glint, and her compliment was worded in a strangely formal manner.
