I have looked around some both here and on google and seem to be getting some conflicting information.

So i was just wondering, has the existence of nrem dreaming been proven or disproven in reliable peer reviewed studies? If so then could you please point me towards them so that i may review the information myself?

I think I have experienced non rem dreaming personally, I have experienced both vivid and non vivid lds in my own studies where i went from fully awake to dreaming with an alarm set for 30 minutes. The non vivid dreams are sometimes more thought than what i would consider a dream, though often it is only my sight which is blinded and i will tend to experience audio, touch, ect. Though a step above that, I will have dreams that are grainy, fuzzy, grey ish.

Right now im looking more for external verification due to having a friend who believes it a fact that it is completely impossible to dream outside of rem, and any studies that say otherwise are biased bs. This is not about winning some argument but satisfying my own curiosity, since i doubt my friend would be open to any evidence differing from his opinion anyways.

Thanks in advance for any replies.
