re: Physicists ... what do you think about fifth dimension travel?

Depends if you are going for the "Scully" or the "Mulder" angle. A combo of both is probably best for balance.

The documentary I referenced is a good start for a general understanding of experiences and especially the audio/visual re-enactments are high quality and accurate compared to some of my experiences and others that I've read.

Academic studies will give you a sterile look at the phenomenon. There are plenty of YouTube channels and websites/threads of personal testimonies as well.

Browse if you're really interested with Google. I'm confident on the direction of my perspective b/c I've had a friend witness me going thru it as well as a family member. Also, a couple friends of mine have experienced similar SP episodes, & they have no reason to lie to me.
