I tend to notice that when people talk about spirituality, they are usually discussing something that triggers awe or another emotion. I feel awe when I contemplate the cosmos, especially when I am alone outside in a dark place where I can actually see the stars. Is that spiritual? I don't think so primarily because "spiritual" doesn't compute.

I'd say yes if seeing the items and imagining their history causes you to feel a deeper connection to the world around you.

When all else fails look up the definition of the word. Spirituality: the quality of being concerned with the human spirit or soul as opposed to material or physical things."the shift in priorities allows us to embrace our spirituality in a more profound way" And from Wikipedia: Traditionally, spirituality refers to a religious process of re-formation which "aims to recover the original shape of man," oriented at "the image of God" as exemplified by the founders and sacred texts of the religions of the world. In modern times the emphasis is on subjective experience of a sacred dimension[1] and the "deepest values and meanings by which people live,"[2][3] often in a context separate from organized religious institutions.

Given those definitions I don't think what you're doing is necessarily spiritual. It sounds very satisfying but not necessarily spiritual. Very artistic. Whatever you do, don't stop doing it if it makes you happy.

I do not use the word spiritual. Caring, empathic, thoughtful, creative, yes.

Artistic, creative, but I would say not spiritual.

I don't know that it's worth labeling it like that. I don't typically use the word "spiritual" because it's such a nebulous term and is wrapped up so much in metaphysics. But you're doing your art. You're imagining a life. Chances are good that the life you imagine isn't reflective of the life that was lived, but that's immaterial because the artwork is really an extension of you, regardless of your inspiration. I think I'd just say you're doing something artistic and leave it at that.

Yes.
