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.
I’ve only had one dream in my life that I could consider at all predictive, and I was so young then that it’s hard to know if it was memory, deja vu, or dream. My ‘creepy’ stuff tends to happen during waking hours.
But I’ve always found dreams fascinating - when I was young, I flew a lot. It was fun.
