Well, to begin with, you do hear your own voice in your head. Like I said above, it is totally normal to hear God's voice in your head. Jesus did it. Jesus said that He only spoke what He heard the Father say to Him in His head.

There are chapters in the book all about the voices in our heads. One of the voices is an evil voice called the carnal mind. You should request the book and click on the carnal mind chapters and read them to get a better understanding about voices in our heads.

The table of contents in clickable in the file and goes right to the section that you want to read.
