If you wanna know, this question has been asked before, but this doesnt mean it would have no use investigating again (who knows what info you can gather). But you should read up to what research there has already been done. I’m pretty sure Laberge did research on this question, since he states that LD’s during the later sleep cycles are more easy to induce. Which is also part of the reason why he proposes WBTB is a very good technique. I guess doing a search on his website would be helpful.
Furthermore if you ask this question it would also be most interesting to know wether the LD was a WILD or DILD. My guess is, most LD’s during 1st sleep cycle are WILD’s, whereas DILD’s more often happen in later sleep cycles. Also the LD’s after WBTB, are those WILD or DILD?
I guess in stead of running a poll, you could ask some people to report their findings on their recent LD’s, and perhaps on their LD’s in the comming time, and report them here. Often when I write down a LD, I do not include in which cycle it happened, so it would take some time for me to report on this (depending on how many LD’s I have in the next few weeks).
I’ve had LDs in all REM periods. For me most happen in the 4th or later REM period. I’ve had maybe 1-2 in the first and I’m not really sure about the second but probably not even one there… And with one very successful tech I mostly got LDs in the 3rd and 4th. With my HI WILD I had a higher chance of getting lucid the longer I slept so after sleeping for maybe 10 hours I’d have an almost 100% chance of getting a LD, but they where mostly very short but amazingally vivid But it’s very hard to sleep that much for more than a few days…
1 (0h to 1.5h after going to bed) : 0
2 (1.5 to 3) : 1
3 (3 to 4.5) : 4
4 (4.5 to 6) : 6
5 ( 6 to 7.5) : 8
6 (7.5 to 9) : 12
7 (9 to 10.5) : 9
8 (10.5 to 12) : 4
There is a problem. Most of my LD’s appear after a WBTB. But I don’t know how to estimate the sleep cycle number after a WBTB. Does the cycle continue normally or does he stop and run again after you go to bed? I don’t know if it has been searched.
My results confirm what Laberge said: LD’s happen at the end of your night. There are theorical reasons to this. LD’s most often happen during REM sleep, and your REM sleep is longer in the last cycles. So that there are more chances you have a LD. It could also be related to the melatonin(?) rate, which is low at the beginning of the night, and increases after about 4 hours of sleep (I’m not really sure of this point).
About my results: there is a decrease in the 7th and 8th sleep cycle. I suppose it’s because I don’t sleep 12 hours every night!
The cycle continues, but then it is not a sleeping REM cycle, you are awake. This means different chemicals in the brain, and you dont dream (the wake process takes precedent). This is also why threre are certain periods during the day during which you might suddenly become a bit tired, the cycle continues throughout the day. Popov used to write some cool stuff on this in his synchronization thread. My idea would be that you dont count the time during WBTB because during that period you do not have dreams.
Ah… but even so, how do you know at what hour you have the dream (or have it begin)? It could have been at midnight, or 3am, or 7am - how could you tell? (Well, unless you guys have this uncanny ability to know the real time in your sleep, which would be impressive!)
I mostly have DILDs and LD’s in cycles 7 and 8 but that’s when I’m not trying. If I read about dreaming before bed, do MILD, lots of WBTB etc. I can LD a bit earlier in the night.
I should know this but do ld’s that aren’t wild’s have to be dream induced? I’m often lucid right from the beginning of a dream and can’t remember anything from before but maybe that’s an illusion
REM sleep durations through the different sleep cycles are statistics. Some people can fall asleep and have a long REM sleep immediatly, if I remember well. Moreover, I looks like you’re napping very often in the afternoon, and it perhaps modify your sleep cycle…
I don’t think that question has been asked before, at least not recently…
so after sleeping for maybe 10 hours I’d have an almost 100% chance of getting a LD, but they where mostly very short but amazingally vivid 
But it’s very hard to sleep that much for more than a few days…
Yes indeed, it would… I’m gonna edit my first post and add those informations…
it is actually the opposite for me most of the time. All the LDs i had during the first Sleep Cycle were DILD’s…
