So the commonly held shared hallucination, while rare, stands as fairly well documented:
Medscape: Medscape Access
And anyone who has used psychedelics or read about them knows that shared visions are common, commonly weird, but common in their own right, and speaks to the power of human mind tethering whether on DMT, LSD or Ketamine.
In the case of time slips, the best story is of the married couple in the car who are suddenly transported to a new landscape where the houses disappear. Their friends in the now invisible house see them get out of the car as they stare around, looking lost staring at trees and then drive off only to return later back at the now visible house. So the options are: time slip or shared hallucination. Given that secondary witnesses are observing them in real time I place the odds much higher on a shared hallucination than them disappearing into time.
