Mormons (LDS) I have a question...

I have a Mormon friend, that said that his 'God' told him who his future wife would be and told him their future children. The girl that was said he knows and is currently with, kinda a situation-ship. Later said he could sense his future children's presences and unlocked something called the spirit realm with his situation-ship. Basically his future... he explained. He said in that space he could make decisions for future him or something like that.

He also said he could see visions. He said he could sense his future kids presence in the room too and said one was behind me, one time. He also told one of my other friends how many kids she'd have in the future.
He said more but i forgot what it was.

In your religion is this a thing or something that might be a thing in some parts of it. I can't find anything online that saying anything about what he's talking about... I don't have anything against The Latter Day Saints I'm just curious. Thank you!
