Does God Have An Orchestra?

The title of this post has nothing to do with its contents except as a preliminary question.
I suppose God has got some kind of orchestra, but that is not relevant.

The question I have just been wrestling with is about whether God speaks either audibly or inaudibly to those of us who are not prophets.
I know God speaks to us through his word the Bible, and that the Holy Spirit communicates through this means whether directly through personal hearing/study or indirectly through hearing/reading the word preached.
I know that I have something called a conscience which usually gives me correct moral instruction, but I think a case can be made that the conscience is subject to manipulation and I suppose it cannot therefore be the infallible word of God to my soul. I have been mislead by my conscience I think. At any rate, my conscience (I don't know about yours) definitely expresses itself in feelings of guilt or joy and peace; not in words, to conscience comes under feeling, not something to put my faith and trust in.
I know God can speak to me through various means and so on, but these are not what I was wrestling about.
I have been wrestling about whether God speaks words into my mind when I am in prayer (or even not in prayer). I have heard reports from Christians with like faith to me, (that also do not claim to be prophets) that they have received audible messages from God relating to some specific point of action. I have never experienced this, but I never felt I had reason to doubt it.
But that is not what I was wrestling about. I was wrestling about whether God speaks words into my mind. Silent words that have no audible components, a still (silent) small voice I would say.
I have long cherished this ability to communicate both ways with God, though I have always been plagued by a lack of certainty as to whether the origin of the thoughts was mine or divine.
It has been for me my strongest fortification of faith when most challenged. I know (and know of) many Christians who share this view. Usually the most committed and spiritual of Christians.
I am naturally sceptical, by training I am doubtful, faith is a struggle. My two-way mental connection with God has been my strongest band to tie me to him.
I have received thoughts to do things that were right and appropriate; things that future revelations and events have shown to have been unusually wise. My conversations with God led to my genuine conversion, my consecration and finally my affiliation with people who have the truth.
Yet it is the people with the truth that cause me to wrestle.
Is it true that God speaks to us through the Holy Spirit only through impressing on my mind the written and spoken word of God directly and indirectly?
If this is so then God cannot have been speaking to me in this way as I have thought he was for so long.
My mind whirred though verses of scripture.
Not one passage came to mind that talked of God speaking to anyone in any kind of voice except through a true prophet, except in very special and unusual circumstances (when it sounded like thunder). The passages that come to my mind talk about experiencing God though his word and his power in my life; not through my thoughts.
It feels like I'm contemplating atheism.
It feels like a betrayal of everything precious in my past.
I am left clinging to nothing but the prophetic writings.
It feels like I am being cut off from God.
How could the experience that has led me into so much good be a false experience?
Yet I must stand on God's revealed word.
What does this mean?
If the experience is from Satan, why would Satan lead me into the very church, perhaps the only church where his deception would ever be unmasked.
There came a thought to my mind:
Satan knew that would be the only way you would justify clinging to this deception.
It was one of those thoughts.
I know it was my rational thought from my brain, or it was claiming its own falsity.
What I had thought were God's thoughts planted in my mind and turned into my own words was actually my God-given brain shooting out possibilities for my will to consider.
Now I know to base my decisions on my own judgment using the wisdom from God, the understanding given by the Holy Spirit and the knowledge given to me through the prophets.
God can give specific counsel in this way, I have experienced that too, and it is much more solid.
For example I became a vegetarian after reading Acts 15; why? because the Holy Spirit caused that the strong injunctions against most of the meat the Christians had available might show me from the text what my action should be in this now horribly degraded world. I can think of many other examples.
I am not to seek a connection with the divine inside me, I am to let God speak to me through his chosen channels; the prophets. Where the prophets are silent, I am free to choose based on my God-given wisdom and God-given preferences.

What about those replies in my mind? What about the people who hear an audible sound?

This brings me back to the title of this post.
I sometimes hear very quiet orchestral music. Riding in the back of the car on long trips Dad used to play classical music and I was always sorry when it stopped. I longed for it to start again, and this was especially the time I used to hear it. I would think it was coming through the speaker system and put my ear against the speakers. It was still there, but no louder.
Why wasn't it louder?
Because my mind was playing a tune to me, unbidden, not thought of; not necessarily recently heard. Not coming from my mouth or my throat, not entering through my ears; my mind was able to play music as if it had its own orchestra. God was not playing music to me, I don't think such a possibility has any scriptural grounds, nor did I get that impression. It has not changed in frequency with my growing spirituality, but rather diminished with the waning of my hearing orchestral music through my ears.
My brain is fearfully and wonderfully made, but my deepest thoughts (or feelings) are desperately wicked; I don't understand either of them.
If my mind can play me music it can answer my questions as if they have origin in an external being, if I expect and hope for that.
Does this challenge the core of my faith?
No, though I was shaken.
I think it will strengthen my faith enormously. No longer will my prayers and actions be guided my own arbitrary foolishness directed by my wicked heart, creating confusion when God sometimes answers and sometimes doesn't. I will direct my prayers to claim his promises, and I know what he has promised he will do.
