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

For instance my father has been dead since 2006 but I have been talking to him since and still do almost once a week. I dont remember all conversations with him but I remember speaking with him. If I re-trained myself in lucid dreaming/falling asleep and keep a journal I could definitely record more of our conversations.

The weird thing is, when I'm talking to him, it's an alternate universe/timeline. It's as if nothing happened and we are still at our original house back in BR. It's always conversations and he is trying to get a point across to me.

ETA: On my dad's deadbed at the hospital he transmitted a very specific message to me telepathically and made sure I understood it before letting go of my hand 2 hrs before he died.
