Maybe I'm out of the loop here, but why would this be a reason to want to be in contact with someone? You can read accounts of this and imagine it.
It's unclear if people getting proper sleep, but don't dream, exist.
It's very clear (to me) that people who dream all the time are getting proper sleep.
My mum had the same dream every night with someone chasing her. She would wake up the moment they caught her. I asked her to describe the surroundings then told her at which point I would enter and scare them off.
The next day she put up a face that explained everything. I laughed so hard.
