I would just like to point out that I created a graph from reading Stephen LaBerge’s book. In the section on the dream cycle.
I don’t have the graph any more, but i could knock another one up if anyone wants to see it.
From this graph I worked out that the alarm should be set to go off around every 42 mins. With this setting, there is a higher percentage of the alarm going off during a number of REM cycles, rather than a Delta cycle (where you do not dream).
There is no point of the alarm going off during any other phase of sleep other than in the REM phase. Of course, everyone is a little different and may wish to experiment with the times of the alarm. But I would try using one setting for at least a week before changing it.
For example, you do not dream for at least the first 90 min of sleep. Therefore, if you set the alarm for 30 min, it will go off at least twice without hitting a REM cycle, and if you’re unlucky a third time just before you go into REM.
If you set it for 42 min, the second alarm will go off in 84 mins. Now, yes, it may miss the first REM cycle, but depending on the individual, may hit.
I very much doubt though, that a setting of 30 min will hit the first REM cycle with the second alarm. That would only be 1 hour of sleep. And if you are the kind of person who goes into REM after 75 to 80 min of sleep. Again, the 3rd 30 min alarm will miss, where as the 42 min setting will not.
The first REM last for roughly 10 mins, you then go back into Delta.
The second Delta phase last around 60 to 90 mins. Then back into REM, which may last 15 mins.
So roughly the second REM cycle will come about roughly 160 to 190 min of sleep.
The 30 min setting should hit this cycle. Unless, the individual REMs at the 160th min, and it last for only 15 mins, in which case the fourth alarm will miss.
Where as with the 42 min setting, there is a much higher chance of it hitting the second REM cycle.
These are of course only calculated guesses, but I did create a very detailed graph, with various alarm settings and the 42min one came out on top as a higher chance of hitting REM cycles, in some REM cycles it may go off twice, the longer you sleep.
Dont take my word for it though, I’m just sharing my workings and theories. Its always best to experiment and test ideas.
Try not get too anxious during the day whilst wearing it. It may be counter productive. Just try to ignore it being there, just think, if it doesn’t go off, then it doesn’t go off. Just dont worry about it. When and if it does, do a RC and continue with your day. Almost ignore it being there, and dont expect a vibration. It has to become routine and automatic.
Dont forget though, when you do a RC ask yourself at the same time, ‘Is this a dream’ Its a much more direct question that,‘am I dreaming’.
‘Is this a dream.’ Do not throw this question away and answer it too quickly, you must think about it. Really think about. Be certain that it is not a dream.
If you dont really think about and say well of course its not a dream, your dream self may do exactly that when you are actually dreaming and you wont become Lucid.
