Hellsomnia

Traverse through the abandoned rooms of your fading memory, you are playing as an insomniac and a melatonin addict and your goal is to find a pillow, a blanket, and a teddy bear in order to assemble your bed so you can sleep peacefully, 

But nightmarish monsters lurk around in every corner and your only way to face them is to take suspicious pills and enter a  dreaming sleepwalk where you hallucinate their form

No fear will haunt you once you find the pills, but only then you beat the HELL outta them
