Should I Dream About What I Could Be and or Do?

I'm afraid that if I start dreaming about what I could be and/or do ... I will feel guilty, and I'll toss my dreams aside (after some of my dreams don't turn out at all even though I've really tried them, which has happened just often enough to make me scared to dream again).

Then there's the whole question of whether my dreams come from You, God, or from me--and how can I know for sure? What if they actually are from You, though I thought they are from me, so I didn't follow them, and now You are disappointed in me not being happy with Your plans and purposes? Or maybe my dreams not working out are my own fault after all, because of wrong decisions I've made and bad things I've done, and therefore I "deserve" things not turning out the way I hoped and wished and dreamed?

And after all, I do live in the 1% world (even though I'm not rich) and I do have a really awesome life compared to the 99% world, so what right do I have to complain, anyway--or need to dream of bigger things?

(And yeah, what about "Take up your cross..."?)

And related to dreams ... learning to ignore the expectations (dreams for me) and beliefs and criticism of others: that's really hard for me. Learning to not wish for and work for others' approval and acceptance and all. Being brave enough to not have to obey anyone but You (who is not nearly as scary as people are because You DO LOVE ME ... and I CAN TRUST YOU!).
