Reddit reviews Mass Dreams of the Future

Yes, there is evidence they are.

There were independent studies in the U.S. and France in which people were "progressed" (as opposed to regressed) to two future eras: the 22nd century, and the 24th century. Remarkably, both groups of people reported seeing things which were similar. The future they saw was also unexpected in some ways, so it's difficult to claim that these people were just "making it up".

One of the researchers wrote a book on this subject: Mass Dreams of the Future. Also: link to book on Amazon

I have an ancedote, too. Soon after my son was born I had a "flash" of what seemed to be another lifetime with him, but the environment and our clothing made it feel as if I was looking at a future era.

Another possible explanation for what you saw is a past life from another planet. I know people who have had vivid recollections of such lives, including lives on technologically advanced planets. On one occasion even I had a brief flash of recollection of one such life.

Yet another possible explanation is a lifetime from the fabled Atlantis. People believe that it was real, and more technologically advanced than we are today. However, due to the misuse of technology that was not fully understood, those people ended up destroying themselves (and nearly eveybody else on Earth too). I personally don't have any recollection of those times, but a friend of mine has.

Good luck, and thank you for sharing!

Edit: about Atlantis.
