Yes, of course it can be real. I have had many such dreams, as have other women in my family, including my JW sister. They come true whether we want them to or not.
The latest one I had involved a grandchild. I saw her nearly drowning, while two people stood by and watched, not helping. Because I couldn't tell which grandchild, I phoned each of our children with the warning. One of my children was at that time vacationing at a lake. He took the dream seriously, as my children have learned from experience to do, and kept a close watch on his child around the lake.
The next day, though, she was a passenger on a small ATV being driven by an idiot older cousin, with another cousin also on board. The ATV flipped over into the river that fed the lake. The driver fished out his brother, but not my grandchild, who is only four.
Miracle of miracles, she pulled herself out using the grasses and weeds in the water. Do I believe in dreams? YOU BET I DO!!!
