I keep being afraid that my subconscious mind is making up personalities to deal with different issues of my own personality, rather than actually having a deity speak to me. Have you had this thought?
Yep. But, IMO, it's not something to be afraid of - it's less important whether it's
true (there are an awful lot of things in religion/spirituality/magic/etc that there's no way to prove conclusively), and more important whether it's
useful. If it isn't useful, you might as well dismiss it, whatever its source; if it is, you might as well make use of it, whatever its source. Being sourced in a deity doesn't make it more reliable/"real", and being sourced in your subconscious doesn't make it less so; either way, it's much wiser to consider it carefully with your conscious mind rather than just accepting it with little consideration, and either way, it's part of your personal reality.
