I dot think that's true. Someone did a study where they observed when people entered REM sleep and later woke them up and asked then how long their dream had been going on. They generally said they'd been dreaming for the same amount of time as they were observed to be in REM. Which pretty much proves they were experiencing time at the normal rate, and their dreams weren't condensed (there's even a myth going about that dreams only a couple of seconds). I suppose the possibility remains that people have many dreams in the REM period and each on just happens to seem like it's the same length as the total REM duration (incrementing each time in a =+ fashion). Not seen that documentary you linked to but I'll post the link to the study if I find it.
