Consider this. Every time you go to sleep you become some other personality that may or may not be you, go into another world, interact with people that don’t exist and you don’t even remember most of it.

And this is completely normal and everyone does that. Nope, no sign of mental illness there.

No, that's wrong. Some people don't dream. If you take something like ibuprofen PM you can have a dreamless sleep. 

Dreams, though, how deceitful they are. Leaving an impact on our hearts and minds even when we know they're transparently fake.

every time you go into REM sleep you dream. you're confusing not being able to remember your dreams with not dreaming
