The URL's being...sources?

I think its fair to say that the "descriptions" of "some" NREM dreams "seem" indistinguishable from REM dreams.

I also note that peer reviewed research papers show that Atonia - or sleep paralysis - does take place outside of REM sleep. It shows a U shaped pattern which peaks before and after REM.

the present report systematically documents epochs of muscle atonia
in NREM sleep (MAN). Although their most frequent occurrence is in proximity to REM sleep, they are present throughout a NREM sleep episode. This gives rise to a Ushaped pattern. The present observations are in accordance with previous reports that epochs with a low EMG level occur in the part of the NREM sleep that precedes and follows REM sleep (4, 5, 12). These findings indicate that a REM sleep episode is not sharply delimited but that it has antecedents during NREM sleep and that it vanishes gradually in the succeeding NREM sleep episode.

It seems that there is no on-off switch between NREM and REM and that there is a transition period.

Which would in my mind fit nicely with how thoughts gradually change to imagery before becoming a encompasing dream. As they do during a WILD.
