In The Tales of Sage & Savant, Dr. Sage and Professor Savant send their conscious minds through time and space to inhabit other bodies. They retain those experiences when they return to their own bodies. Part of our theory behind this mode of time travel is the current theory that thoughts are quantum objects rather than physical aspects chained to the cerebral matter of our brains. Recent tests have aimed at proving quantum objects can travel through time. Therefore if thoughts are quantum, they would also be able to travel through time. This is great fodder for Science Fiction!
