i had it once but the environment was surprisingly tranquil.
it was night, just got off the elevator at my floor in the apartment complex, was riding with my dog. walked down the long hallway like usual. i really can't remember because it happened a long time ago, but i heard unnatural moving from behind. behind me, all the hallways were gradually getting darker, and then it happened where i couldn't move. this was the scariest experience ever because i seriously couldn't move, until i was like, completely shrouded in darkness
