I don't usually post in this section, but I'm having a major dry spell and so am trying out new techniques. Up till now the DILD was the only thing that I had to do, just think about lucid dreaming during the day and then go to sleep and this would, a few years back, infallibly give me a lucid dream. Not anymore as it happens though

So I read the guide on this forum for DEILD's but noticed it contradicts itself where it states that it is best to attempt the said technique when you wake from a dream - and then it goes on to say that you won't be able to enter a DEILD if you've just finished an REM period, which really confused me: if someone could clear this up for me it would be great

Secondly, it seems like all that is required for a DEILD is to wake up and then lie there, remaining conscious, and a dream will always form. I find this very hard to believe; all my WILD and WBTB attempts so far have ended with me just lying there, fully conscious, for about forty or so minutes with no dream onset in sight. So is it really that easy?
