Always on the search for new concepts to place into fantasy or science fiction writing, I came across the website by Cynthia Sue Larson. Ms Larson writes about her experiences with actual reality shifts in relation to how a person's consciousness changes the physical world around them. Her Reality Shifters website contains a myriad of information about the concept which I found to be quite interesting. You can make up your own mind.
