I started this one with the Lord of all Fears, the Boogeyman himself.

Bogyphobia is the irrational fear of the Boogeyman. I used several depictions of the mythological monster to create this, most depictions of the Boogeyman is of an extremely tall and thin humanoid entity with either pale or dark skin with elongated features as well as looking like a cadaver/corpse. There are several legends of the Boogeyman and its abilities, among them its his affinity for darkness, capability of teleporting through wardrobes, under people's beds and dark corners, feed on people's fears and shapeshifting tending to turn into what people fear the most and only showing his true form to those that are afraid of him alone.
People suffering from Bogyphobia tend to distrust of any shadow, hallucination and/or shape that they may see at the corner of their eye believing to be the sadistic beast itself.
I gave him the red eyes due to most depictions of 'evil' or 'dark' creatures tend to have bright red demonic eyes. The tendrils is an idea of its potential to shapeshift, reach prey or even make himself more intimidating.
The clothing is the typical idea that a coat and hat on a chair almost makes it look like there's a figure there, another thing that triggers people with Bogyphobia to enter into a state of paranoia

Edit: Made him slightly brighter, he was too dark for any details to be identified.
