We all engage in some form of magical thinking, in which we act as if something is true despite the lack of evidence to support it.
This is not inherently bad as long as the magical thinking serves you, does not cause problems for you and others, and is not part of a limiting belief that does not serve you or the world.
I have believed in one form or another that I have had a higher mission that I've been working towards for the last 20+ years, I see this as my fate, my higher duty beyond caring for my loved ones.
There is a lot of metaphysical magical thinking tied to this belief, but it is my driver, my higher purpose, and only after I have passed will I be seen as either mad or genius to have been directed by this mission.
If good comes out of it, it will have been a self-fulfilling prophesy, this in no way will mean that my magical thinking was true or false, only that it served me, and being a pro-social set of beliefs, whether it served the world beyond me.
Everyone has magical beliefs, everyone, Richard Dawkins, and other atheistic types all have magical beliefs whether they choose to admit it or not.
It's whether that magical belief serves a purpose higher than yourself, or even whether it serves just you and does not negatively impact your world, this is the benchmark.
Believing you are cursed or have bad luck is a magical belief and a self-fulfilling prophecy that does not serve you unless, of course, it serves a higher purpose.
The fairytale trap is a form of magical thinking that many young people fall into, that their destiny of fame and riches is going to come knocking and they don't have to get out there and wrestle down that destiny through action.
Magical beliefs are necessary and there is no way of knowing their truth in the scheme of things, it's whether it serves or hinders you or those around you, not only in the short term, but overall.
But even negative delusions can be stepping stones to your service, a stage that must be passed through. The problem comes if you are taking advantage of others now for a perceived payoff in the future.
Magical beliefs can soothe our soul and if they are helping, good.
If they serve a higher purpose, great, if they soothe your soul, be soothed, as long as it is not enabling an attitude or actions that are hindering you or others, if they are stopping you from fulfilling personal, communal, and societal obligations.
Think little of whether it is factual, there is no way of telling, think about whether it serves a higher purpose, whether part of that belief is a hindrance to the world around you.
If the magical thinking is shared by a group or section of society. Ask if these magical beliefs are beneficial or harmful. Like the magical belief that the world is cursed and therefore should be and will be destroyed, does this serve the world, does it serve future generations, or does it serve individuals whose actions are actively harming our planet?
