Soon, a taradiddle of gun re-cocking echoed through the space.
"What's going on?!"
"Mark just had a nightmare."
"Damn it, I thought monsters were crawling up."
"Stop fucking shouting, it's frightening."
"..."
Turns out someone just had a nightmare.
A false alarm, you may say.
There was a quick pacification.
Nobody made a big deal out of it.
...
There was no light to differentiate between day and night in these ruins.
In the morning, bizarrely, the intuitive hunters happened to wake up late.
Each of them looked fatigued with dark circles under their eyes, and several of them woke up soaked in cold sweat.
"Damn, I was chased by zombies in my nightmare all night, I couldn't get away no matter how hard I tried. It wore me out completely!"
"I had a nightmare too. Dreamt of jumping off a cliff, nearly scared me shitless."
"Oh, I thought I was the only one with nightmares. Damn, there's something wrong with this ghost of a place."
