I can only see the first 2 and a half lines of this post. There is a See More>> but it does not expand.
After I started using the internet, I found out about the barefoot lifestyle. I once had a dream where i was in a school playground, in my bare feet, with no explanation for this, and just feeling embarrassed.
I have a few dreams where I meet up with a friend, or a former friend, and we are happy again.
Another dream of mine, put me in the place where i worked at that time. A co-worker or 2, that I knew, were in the dream, the difference from real life, was that I was doing a different job, for another department.
I think the brain just sometimes takes our experiences or thoughts throughout the day, and creates scenarios and makes dreams from them.
If you take my most watched films, or tv series, I don't ever recall a dream, where I was in any of them worlds, or acted like a character from them.
If you want to believe that your dream was a sign of something, then you are free to do so.
Remember i dont see your full post, and I am not sure if you are asking a question about this, but these are some of my experiences, and my thought on why it happens.
