Phenobarbital is a barbiturate. Kendall's sleep disorder was most likely treated with a barbiturate. When barbiturates are discontinued, patients often spend excess time in REM sleep during the next night or two so as to make up for the lost REM sleep (REM rebound). During the rebound period, there is increased dreaming that may cause restlessness, anxiety, and nightmares.
