(noun)
A surreal, unsettling feeling where the world suddenly seems “off,” unreal, or slightly distorted — like a mix of déjà vu, derealization, and emotional disconnect.
Simerio is that moment when everything feels familiar but wrong at the same time, leaving you unsure if you’re fully present or stuck between two versions of reality.
Examples:

“Walking down the empty hallway at night gave me major Simerio.”

“I randomly got hit with Simerio in the middle of class and everything felt unreal for a second.”

“You ever get that weird foggy feeling where life glitches? That’s Simerio.”
