Dagto, I read through the entire thread and understand you have not had a single LD for so many months. I admire your persistence, and the many advices given by others are all very useful ones, but I have to tell you this – you are probably on the wrong track.
In the old days LDs were indeed random encounters. Today, with so many options out there it should no longer be pure luck! From my experience, assuming you are on the right track, then you should experience at least a few LDs within weeks, not months. 4-6 months are the times needed to master LDing so you can induce them almost at will, on a near daily basis.
I believe you need to work on a bed-time technique instead of hoping for things to happen. People already suggested WBTB, MILD, and so on so I will not repeat what has been said before. I recommend you to check out this SILD technique, and put some serious effort in it. It is very simple to learn, and takes only a few minutes of your time. However, if you do it correctly it is not impossible to induce LD/OBE on your first attempt – I’ve seen hundreds of such cases. Below is the link to the technique. Be sure to read it thoroughly so you don’t miss any details. Good luck!
