This dream is a warning about a storm coming, probably within a Bible study group of some sort. It is all about teachings or doctrines. In dreams and visions, a ball speaks about an opportunity to preach or teach the word of God. It is also applicable to non-spiritual situations when a person uses an opportunity given to them to say how they feel about something, like in a job situation, like in a meeting, or during a course.
In this situation, I think it is about spiritual matters. So the storm will be caused when someone uses an opportunity (the ball) to reveal how he or she feels about something. However, the ball is gray, indicating that it is the truth mixed with lies or untruths. So this will probably be a false doctrine. It is also made of dust which speaks of the flesh. It was born in the flesh of man and is not from God.
The lounge speaks of you discussing the dream with your husband. So he is involved as well. I think God wants you to discuss the incident with him because he might be able to give you advice.
You will be directly involved. You will be in the center of this. It will be a bad incident for you but you will survive and this doctrine will be destroyed, probably by you. Your rebuke and the lifting of your arms destroyed it. It was aimed at your heart (chest) because this is where the enemy has the most success. See Heart in the Dictionary. It represents our soul. The enemy always attacks the soul of man because this is where we are vulnerable.
The window speaks of God giving you special insight into the storm that is coming.
The fact that the ball came through the window speaks of the enemy being sly by getting to you through a soft spot, an area where he or she or an evil spirit thought you might be vulnerable.
So the attempt to change your mind about the word of God or a specific doctrine will fail. You will not compromise. This person will fail.
By the way, is this a past event already or did it not happen yet?
