So I found this website today, claiming a theory we are all living in some sort of bisecting timeline, based on shared memories that don't fit the current timeline.
Starting with people remembering the death of Nelson Mandela in prison years ago.
How about the Challenger explosion- 1984 or 1986?
Berenstein or Berenstain bears?
Chartreuse- maroonish or greenish?
Jif or Jiffy Peanut Butter?
Location of New Zealand?
Did you watch Billy Graham's funeral on TV many years ago?
All these and many more are listed with discussion on the website, people take this VERY seriously!
Do you have any of your own?
