Could be. Only time will tell I guess. When I can afford it or maybe the real big maybe is if TSA ever calms down I would like to check out the pyramids for chip marks. I know it has been thousands of years but well this was another vivid dream and there have just been so many lately.
Not that it matters so much what I believe, but I do believe people can get a glimpse of the past, as well as the future.
IMHO, both primitive methods and laser space opera methods were used to move things around in the distant past on this planet...
Keep on remembering your dreams....
Also pyramids may have been erected for protection. The whole populace would fit in some of those things.
Just one of the many ways to look at dreams is the Dream Dictionary
"To see a pyramid in your dream, symbolizes longevity and stability. You have built a solid foundation for success. Alternatively, the dream suggests that major changes will occur over a short period of time.
To dream that you are climbing a pyramid, indicates that you will find gratification and fulfillment through perseverance."http://www.dreammoods.com/dreamdictionary/p3.htm
