You're very welcome. I was happy to be able to provide you with biblical references for how God confirms His messages for us.
And you're very right that the number 3 has much spiritual significance. The number 3 is spiritually the number of completion and perfection. It is used throughout the bible to denote divine perfection. So it would make sense that God uses the #3 to confirm His messages to us.
And how wonderful to awaken from such sweet dreams! It is a good sign that you and your H get along so well and so comfortably in your dreams. It seems to signal that God is working behind the scenes on your behalf.
