Welcome HolographicDNA...
I humbly suggest that you train yourself, if you haven't already, to sing out loud with gusto...
To sing with soul & sing from the Heart...
Practice this until it becomes second nature.
Then, the next time those dark entities are attempting to scare you (don't fall for it, that just gives them power that you should keep for yourself), sing strongly & confidently. In my experience, they tend to melt away instantly & be replaced with beauty that will make you cry in gratitude.
Sing what, you may ask? Anything & everything that resonates deeply with your heart & soul.
Take up a good, regular meditation practice of some kind too...One that will help you stay calm, focused & serene whether in the midst of heavenly worlds or hellish visions & torment.
Please be mindful that there is no easy, overnight fix for this. It takes commitment & practice & it takes being very patient with yourself, forgiving yourself & loving yourself.
Just my two cents to try & help a fellow hyperspatial traveler.
May peace be in your heart always.
Freedom's so hard
When we are all bound by laws
Etched in the scheme of nature's own hand
Unseen by all those who fail
In their pursuit of fate
