Wheat fields are more mystical than fields of other crops. You are 7,000 times more likely to meet an old god or see a portent of doom in a wheat field than in a field of like… soybeans.
For your consideration: cornfields
Cornfields are less mystical than wheat fields but more mystical than soybean fields. Two-bit monsters congregate in corn fields to eat people, but their power is nothing compared to the things that manifest in wheat fields.
Have been in both wheat and cornfields; can confirm. Cornfields host monsters who eat people. Wheat fields attract old gods.
For me, it’s the sound.
The sound of a wheat field wakes something up in me, like the soft but powerful “shaaaa” of wind through a proper amount of trees, the wind coming to you and singing it’s song to you before it greets you.
Corn doesn’t sing with the wind like wheat does, it doesn’t dance and flit with it, not in the same way.
Yeah, but walk through a tobacco field and man you gonna feel something else on the far side of it.
