It's the space between day and night when they come.
When my consciousness fades away to sleep, and I can no longer defend my mind.
These organic monsters invade my psyche and fill it with images and emotions of horror and fright while I rest.
When I wake the residue of fear, terror and dread linger until I'm able to rebuild my mental defences.
I stay awake as long as possible, so I can fall asleep quickly - when the space between day and night is small.
I used to look forward to sleeping, but now it scares me.
