Mostly harmless
I am at a loss to explain why you are linking to stuff about REM sleep (which is basic knowledge and not unknown to me). None of it refutes that I remember most of my dreams, at least one a night, every night. Nor does it explain why you claimed that 'we' don't remember most of our dreams, nor what dreaming has to do with immortality.
Perhaps Jabba is working up to a claim that when we wake up each day we don't remember our previous life.
