Interesting, but nothing really new. One big flaw is the fact that of the millions of people on anti-depressant medications (many of which inhibit REM sleep as a side-effect) none show any inability to live their lives normally. Certainly they don't wander around an open field like a dumbfounded rat.
There are also patients that suffer brain lesions to the parts of the brain that induce REM sleep. Again, they are able to live normal lives without having dreams.
But those REM deprivation rat experiments have been going on ever since the 60s (Fishbein, 1981). The only new thing he's done is jack them up with amphetamines. But injecting rats full of amphetamines after days of exhausting torture isn't going to return them to a 'baseline' level of ability, it's just going to tweak them out more. That's a really absurd assertion. Rat studies like this are also plagued with external validity problems.
In a review of the role of sleep in memory i did i concluded that REM sleep probably plays a role in the consolidation of emotionally charged memories. In fact i think this guy has it slightly wrong, if there is any truth to this, dreams don't act as 'threat rehearsal', but as 'emotional situation rehearsal'. I mean sure we have lots of bad dreams but we also have lots of good dreams - sex, relationships, adventures etc.
For instance, Hu, Stylos-Allan and Walker (2006) showed that in an emotive picture stimuli recollection task, pictures of high emotional arousal were remembered 42% of the time more after sleep than a similar period of time spent awake. This suggests of course that sleep has some role in consolidating emotionally charged memories. And that includes pleasing pictures as well as upsetting ones. If he was right, then they would only remember the threatening pictures.
In EEG studies, Zebra Finches were shown to display the same patterns of neuronal firing when they were singing, as in periods when they were dreaming - suggesting they replay their songs as they sleep (Stickgold, 2005). There's no 'threat rehearsal' in a Zebra Finch singing a song, but it may have some benefit.
