God has spoken that way to people in the past but it should be seen as a rare event. We should be cautious not to see a dream or a feeling as something that necessarily comes from God. Especially if it's about something you want to do anyway.

When I pray I close with asking God, "What can I do for you?". Once after I did that I felt the words of God saying to me, "Lead a Bible study." So I did.

Usually God speaks to us through his word. That's where our moral instruction and moral direction should come. God would never want us to sin. Ever.

God can direct us through the Holy Spirit. There were times I was thinking about doing something and I prayed about it. Afterwards I got the sense that I shouldn't do it. So I didn't.
