PMH Atwater is amazing to hear and see on youtube for free. Check out the linkĀ https://youtu.be/v1mD10-CN34 for starters. Even skim through it. She teaches at the Monroe Institute.
Some of her programs are online as well. She shares more about that at `17 min into the talks. She talks about timeshifts...and she says 'we can create them.'
There's lots more but she's written a comprehensive book on NDEs. For those who feel they can time travel in their car, she has some tips about that.
