Maybe it's a subconscious. Some feel dreams can tell things. Some thing they're just random most of the time.
With me, I usually tend to dream about animals dying shortly before losing pets. It's happened around 6 times, with a total of near 9 pets - including dogs, fish, and rabbits. But so far, those are the only ones that seem to be reality based.
So, sometimes, maybe they are telling you something.
I have had recurring themes in my dream with the same plot, but different players and settings lol.
1. One is dreaming of having an emergency, and I need to call someone, but no matter how many times I dial, I always get the number wrong. I know the number, but my fingers just never press the correct ones. I end up having to start over, and the same thing.
2. Another is dreaming of being trapped in my house, and I have to go out of a window, but as much as I hit the glass, I never seem to be able to break it - until after 30 tries, if I succeed.
3. Finally, there's dreams of being chased by someone, or something, and running for my life. Sometimes it's monsters. Sometimes it's FBI agents, and sometimes, it's serial killers. lol
Why I have these dreams, I don't know. All of this stuff is the last thing on my mind when I all asleep. You'd think some of my dreams would involve some men I am attracted to, since I think about them a lot. But rarely do I have good dreams involving them. lol Last dream I had of that nature was last May I think.
