Fright Night at the Terror Tunnel.
It appears out of nowhere, especially in long hallways, tunnels and large rooms.
It doesn't matter if it is daylight or midnight, or summer or winter.
You just need to walk down a corridor or stairwell and it appears out of nowhere and spins in your direction carrying you to a frightful place.
Here you will see horrible things. Here you will hear horrible sounds. Here you will smell horrible stench. Here you will feel horrible things. All this is beyond skeletons and ghosts and goblins and witches. And beyond normal fears during Halloween because there is no escape.
When you experience such horror, you feed its "fright hunger". You become a part of the horror. The horror is a part of you that cannot be separated.
From this point on, you are the one who frightens new victims with your own horrible sight, your own horrible sounds, your own horrible stench, and your own horrible being.
You empower the Terror Tunnel so it may grow and appear at many unsuspecting locations at unusual times. You spin out of control with it sucking in innocent people who cannot escape its - your - vortex.
The new victims become a part of you - The Terror Tunnel.
