Oddly specific, mundane things that are aligned with the 15 fears:

The Eye- Making deep eye contact with a stranger on the platform as the train pulls away.

The Hunt- Wanting something so badly that you can’t stay still anymore.

The Buried- Trying to get your phone back when it falls between your bed and the wall

The Vast- Being a child and hearing about how unknowably large Chuthulu is for the first time.

The Flesh- Looking in the mirror and realising your body’s changed since the last time you really looked.

The Lonely- Realising you’re the only customer at the supermarket.

The Corruption- When you see one ant but once you’ve focused on it you can see the rest of them.

The End- Holding an antique object and knowing that it’s original owner is long dead.

The Desolation- That gut wrenching feeling when you’ve lost something you know you’re not going to be able to get back.

The Stranger- Looking into the eyes of a loved one and not being able to see anything you know in there.

The Spiral- When you say something loud enough to be heard and absolutely nobody processes it or responds.

The Dark- Straining your eyes to try and see something at the end of an unlit corridor that you swear you could almost see.

The Slaughter- Ripping up a letter with your full name and address on and throwing it in the bin.

The Extinction- Being the last player left alive in a survival game and realising that in another life that could happen for real.

The Web- That burning, guilty feeling after you’re manipulated into doing something you didn’t want to do.
