With your first time the exception? Do you mean that in that one you did have lucid powers?
If thats the case you shouldnt worry too much about the current ‘trend’ of limitation. Maybe your first time your rational mind was unprepared, but now it has associated dream-world w/ reality and the limitations with it. That may not be it for you, (its how it is w/ me), it could just be flukes - depending on how many ‘limited power’ LD’s youve had, i guess.
As far as waking from not-so-limited LDs, it could be that your rational mind panics, your consciousness not being used to it. Anyways, it seems like a ‘beginners disease.’ Eventually, a successful manipulation will not surprise you as much, you will be able to stay awake to observe it, then able to stay awake to repeat it (near-mastery if all successful) or try other things then able to stay awake long enough until you start to naturally wake (in which case you’ll have to learn how to restore stability or something).
Personally i am quite limited in my LDs, i dont try much very often (never comes to mind), i dont do much that some may consider ‘impressive’ or whatever in my LD’s, I just act normal, observe for the most part. Im down with that, and they are long enough that several times i have to ‘save’ from natural waking (mostly natural) through stability technique. So i guess thats just about the only skill i have near-mastered, there.
Personally, a DJ is valuable. If i stop doing it, before long my recall will diminish to a lesser quality if not all-of-a-sudden vanish. Luckily if i pick it back up the recall comes back quickly. You might wanna try a ‘vague’ DJ for awhile to see if your recall improves. Then, you can make a judgement on if it is worth keeping a DJ (something tells me you’ll think it well worth it). Maybe you can write it in a way that only you will understand what it meant and whatnot. I must warn you, it does take time and its a relative hassle to get up in the morning after waking - but well worth it compared to most-likely forgetting parts of the dream after having more dreams because of just going to sleep. But, considering the time it may take (depending on how much detail you want ‘saved’, and your memory) you could think about ‘in my next dream i’ll LD’ or something, pull a MILD/WBTB maybe after hitting the forums (or a book LD-related) for 5 mins or so. -At least that potential is part of what gets me up to find my way to the pen and paper.
Or you can just keep a DJ here, where its anonymous (<an oft missed perk of hitting these forums)…
