That’s bizarre.
I’ve had dreams of people I recognized but know I never met. I’ve read that people in our dreams are actually aspects of ourselves. The people stand for something.
Some dreams are predictive, but most aren’t. However, I have had dreams about things as prosaic as me bringing home a stray dog: In the dream I saw my dad, who was still alive at the time, pointing out a struggling dog that looked like it was drowning in a river. I started calling to it and it managed to swim over to me and I fished it out. A really short time later a stray came to my house (I had seen him before in real life and he looked like the dog in my dream) and I adopted him.
