Congrats ND :thumb_up:
I just noticed this thread, or I would have chimed in before. I lucid dream every night... and have done so for as long as I can remember. 4 decades or so.
Looking at your hands is useful to
become lucid. I prefer looking at my palms, but I won't tell you what happens because if you try it, I am interested if you have the same effect without me planting it for you.
For
maintaining a dream after getting lucid, though... try
spinning. If you can spin a couple times before the dream washes out, it usually solidifies a great deal. The 5 senses stuff is good, but I find that commanding the dream directly is best. If you need to speak out loud, do so... after a while you can just will it. Make a firm command that the dream solidify. It will.
For someone at your stage of the game, lucid dreaming is a lot like walking on a tightrope... with waking up on one side and falling back into normal sleep dreaming on the other. Get too excited and you will wake up. Get too comfortable and you will fall back asleep.
Thus, the key is to maintain a curious but detached mental state. Stay curious and keep being active, but hold back the enthusiasm enough that you don't come out of the dream. It is a bit tricky and somewhat counter-intuitive... but it is easy enough once you get the hang of it. When LDs become normal for you, you won't get so excited. More like "Oh yeah... I'm dreaming... okay what did I want to experiment with this time?" not "OMG!!! I'm LUCID!"
If you are not familiar with Lucidology, it is kind of neat and explains a lot of WILD and AP techniques that work well. Last I checked you could watch 10 of their vids on YouTube for free.
https://www.youtube.com/playlist?list=PL872CCEF527B70ED7 Looks like it is 9 vids for free and they are missing a few from the order. 9 out of the first 12. Oh well, maybe you can find the rest somewhere else. I know they have a paid program that costs $
(never took it so I can't say the value)
But there is literally a ton of info on dreaming out there. You could fill a Kindle with just books about Lucid Dreaming, OOBEs and Astral Projection probably without even spending a dollar. As I remember there are a bunch of these books up here on the Nexus for downloading. Go to the splash page and one of the links should take you to our "library" and there are certainly a number of decent books there.
Good luck. Have fun...
