Something about loneliness and different realities... It took some inspiration on things like "The Fog", Silent Hill, Resident Evil and Lovecraft as always... I don't know but I feel theres a lot of "At the mountains of Madness", "The Call of Cthulhu" and "The shadow over Insmouth"...
means alot
I love that shadow in the rails too and how it is, and so the birds
Glad you liked so much
