The Holy Spirit speaks to all people. John 16:8 says: “ And when he (the Holy Spirit) comes, he will convict the world concerning sin and righteousness and judgment.”
God speaks to all people. The decisive factor is how we react to this. Do we want to open ourselves up to him or do we barricade ourselves in and want to keep him away from us?
The Holy Spirit causes us to have a genuine interest in God. So the question is: do I want to know more of God or am I just questioning him?
