This is interesting. I have heard that same message in recent months....THIS IS ONLY THE BEGINNING. As far as the details of your dream, I really don't know. I have had dreams that I didn't post due to not knowing if it was just personal to me or something that might apply to others. Here is one I had on April 21 (I try to write stuff like this down and keep a record):

I was holding a baby, and it slipped out of my hands and fell into the water. The baby's head was going under water, and I was trying to pick it up, but I was like froze in the dream and couldn't move. I was afraid the baby would drown and was trying frantically to save it. I started screaming, SOMEONE PLEASE HELP ME! Then I woke up...with my heart pounding in my chest.

I have experienced some times lately.....waking up because I couldn't breath...gasping for air as you seemed to be saying. I have come to believe that the evil one is messing with me. So when I pray before bed, I have included asking God to bless me in rest.....and it seems my rest is more peaceful. The thing is....even rest (sleep) is a gift from God (Psalm 127:2).

Just thought I would share that.
