Sleep phase (3)

Ross

I believe the answer is:

rem

'sleep phase' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for rem that I've seen before include "radiation unit" , "Phase in sleep" , "Sleep stage when dreaming occurs" .)

I've seen this clue in The New York Times, the Newsday, the USA Today and the Penny Press.
