Which studies do you refer to? Some of the old REM deprivation studies have been questioned due to problems with set and setting, as well as the deprivation methods. Of course, going without REM is almost certainly bad for you anyway. There are some elegant rat studies (with control rats awakened exactly as often as the REM deprived ones) that show that selective REM deprivation is indeed quite nasty over the long term.
