Spirituality is a bit of a vague term. In the dry sense, spirituality is a collection of emotions, conceptions and experiences revolving around one’s “connection” to the world at large. So, spirituality’s specific ways of manifesting definitely have a tight link to ones own personality - how they enable it, how they process it, and to what degree they draw conclusions from it.
Ultimately though, I think mysticism and spirituality is just a complex emotion / experience like everything else. It stands out because the emotions / experiences tend to be in context with big questions no one seems able to truly answer.
