REM is during stage 3 and 4 where most of the dreaming occurs.
There are five stages of sleep. Stage 1 being the one you first enter, then followed by stage 2, 3 and 4. As you descend into deeper sleep your brain frequency slows down. In stage 4 can it be slower than one cycle per second (delta sleep). After some time spent in stage 4, about 25 minutes, you return to stage 3 and 2, then straight into REM sleep. About 90 minutes has passed now since you started sleeping. 5-10 minutes is spent in this stage before you go all the way down to stage 4 again (also called non-REM sleep). When approximately 90 minutes have again passed, another REM-period start. This time the REM sleep lasts longer. And as time progresses less time in non-REM sleep is needed and more time is spent in REM sleep. After 4-5 hours you don't go lower than stage 2. Vivid dreaming takes place in REM sleep, so the more you sleep, the more time is spent in REM.

It depends on the person, and the sleep, but the first stage averages at about 90 minutes, with stages 2-4 taking on average 100-120 minutes. The cycle generally proceeds from NREM (non-REM) stages 1-3 to REM (stage 4), back down to NREM, and back to REM, several times a night, generally ending in an REM stage before awakening.
Most dreams occur during the Rapid Eye Movement (REM) stage of the sleep cycle. Dreams do happen in other stages of the cycle, but those in the REM stage have had more study. See attached link for further information.
No. Once the person hits the snooze button, it should take them about 15-30 minutes to hit REM once again. Depending on how heavy a sleeper you are or the sleeping conditions, you might be able to hit the REM stage in under ten minutes.
REM stands for Rapid Eye Movement and signifies the deepest stage of sleep.
none. if you can not sleep then you suffer from insomnia. The most restful sleep comes during the R.E.M. stage known as rapid eye movement. This is the stage you dream in. It takes about 2 hours to reach REM sleep.
