God is a personal God, so He speaks to us in different ways according to what we most need.
For me, God speaks as a wise and loving Father, because my earthly father abandoned me as a child.
Don't think you're unspiritual if God doesn't regularly speak to you through dreams and visions. Sometimes I have prophetic dreams and other supernatural experiences, but usually God simply speaks to my heart in a calm, kind, firm voice. He gently, yet decisively (and with a sense of humor) directs my path, providing advice and insight...the way a Father would.
Any form of communication from God is legitimate, and the more dramatic ways aren't superior.
