Whether it be the ceiling tiles in the classroom or the hospital tiles in hospice, everyone has a memory of tiles tied in.
These little square pieces that can trigger a violent vision.

However, it might not be physical tiles either.

They may be tiles your run across as you try to escape from the monster your mind creates.
The pieces falling out from under you, giving way to an immense fear.
These tiles are background characters, always looming.

The tiles we see are mere placeholders in our minds for our most substantial moments.
Do you have memories of tiles?
