My Boogeyman is actually my interior evil that manifests from time to time when I don't nourish the goodness and feel alone. Then, not only does the Boogeyman speak for me, but he also closes my ears and and my eyes and opens my mouth and posture, much like the Boogeyman of Dr. Jekyll ( Mr. Hyde ).
Jesus dealt with his Boogeyman three times in the wilderness by obedience to Goodness. It does no good to believe that the interior Boogeyman is not there with me. He is always there.
When I went to a silent retreat once on an Ash Wednesday I was assailed with a dream about my collection of sins: sins of Commission and Omission. They came falling down from the sky like large raindrops with labels. The recognition of them is liberating in a setting that promotes goodness and forgiveness.
When I was a little boy I always looked under my bed to make sure the Boogeyman was not there. He was never there, or anywhere else outside of me. Having now found him, it is possible to keep him more or less in check by suffering through the sins of omission and commission and striving to nourish the goodness in preparation for Easter Day when my load and my cross is shouldered anew !
