It’s not Halloween without a Boogie Man in your closet.
A Boogie Man can come in more than one form. For instance there’s this here classic disco Boogie Man:
– I’m you Boogie Man – KC and the Sunshine Band – 1976 –
However there is also this more menacing heavy metal boogie man as well:
– I’m your Boogie Man – White Zombie – 1996 –
Let’s keep this Halloween party going! Go ahead, pick your poison!
Fearsome Beard 
KC! ALWAYS!
No lack of Boogie men here or in history/literature. They serve a sort of purpose.
