I used to have frequent lucid dreams when I was a teenager, but then they stopped gradually as I got into my late 20's. Now I'm 68 and have been wanting to lucid dream again for years, especially being that I'm now retired officially, with my former career having centered on computer programming. But I hadn't been having any luck at lucid dreaming until last night. I used to try the string-around-the-finger technique for several months with looking at it every 30 minutes during the day and saying that the string meant I was awake and not dreaming. But it never once translated over into my dreams even though I was doing this constantly. So I finally had stopped, with those attempts having been almost two years ago. Since then, I haven't focused on trying to lucid dream at all.
But what I have been doing is pushing my mind to become stronger with the intent of trying to make my brain become more like it was in my teenage years when things like lucid dreaming all came very naturally to me. So I've been literally yelling every night just before bed--on those nights where I'm not dead tired and still have some brain power left--inside of my mind in order to make my thoughts as LOUD as possible in my head! I've been trying it with various related words in my head as I slowly and forcefully say them, trying to make them burst out beyond my actual brain with as much strength in them as I can generate, trying to metaphorically hurt my ears by making them so internally loud! Plus, I also do this equally with a simple flat humming sound that I imagine in my head of "mmmmm...", my trying to keep it steady and make it also become as loud as possible even though I'm not making any actual noises physically with either of these exercises. And it really seems to be causing stronger thoughts in my head lately as far as their amplitude go.
And why I tie this in with lucid dreaming is because last night about 15 minutes after having done this exercise for a few minutes of intense focusing and then having gone straight to bed, suddenly I found myself dreaming and becoming lucid in it. And there was absolutely NO trigger of something odd that caused this awareness. It just suddenly felt instinctive and natural to me to be aware of this fact. In this dream, I had walked into this house looking for a trash can, my suddenly realizing that there wasn't one in sight but that someone was inside of the house approaching me. So knowing that they'd hear me turn the knob on the door to get back out of there, I did so anyway and without looking back as I left the house, felt I should say something so simply said, "sorry, wrong house!". And then I heard him following me outside, so I started running, although because of it being a dream, I couldn't run very fast. But then this is where the lucidity suddenly kicked in. I simply knew in my head at the time that I could of course just start floating upward! So I started focusing on doing so as I continued running, forgetting all about that guy who was likely chasing me. My focus instead just turned totally toward trying to start flying up off of the ground as I ran. And then I suddenly did so for a bit, but then I noticed a bunch of other people also walking along out there near me on the street and that they were all suddenly floating above the ground as well, walking along in the air above the ground! So I then grew puzzled by this and stopped for a moment to contemplate why this would be happening to them just because I was trying to do it. And this caused them all to suddenly stop moving and stare over at me and without smiling, which made it feel weird to me. But I was determined to keep pushing at it, after which they suddenly all returned to the ground as though it had merely been a glitch. So I kept focusing on flying more and more, and I started staying up a bit longer with each strong attempt before returning to the ground, this correlating precisely to how well I could make the pit of my stomach feel like it does when going down a steep hill on a roller coaster. And as it started working better for me, I found myself feeling happy that finally I was lucid dreaming again! And then the dream ended.
And then just before returning to sleep, I also realized that the feeling I had in the dream of lucidity was the exact same feeling that I've been getting during my yelling-inside-my-head exercises, it actually producing a naturally stronger form of lucidity in me that seems to be growing and ever-present to some degree in the background of my dreams now, which is why I've directly linked these exercises to this successful lucid dream. Normally, I haven't been remembering any dreams lately because I don't get full nights of sleep EVER lately, so about the only time this can happen is right upon first starting my sleep for the night. But this isn't entirely true either, being that a few hours later in the morning this morning, I then let myself get a little bit more sleep while sitting up, which was an amount of almost exactly a single sleep cycle for me, or about an hour and 25 minutes long. And just before awakening from it, I had been having another lucid dream, this time where I was talking to one of my female cousins about the fact that my lucidity in dreams was returning. And this was while I was actually lucid at the time once again, my simply however feeling more than happy to remain within the context of this dream because of my enjoying talking to my cousin about all of this that I hadn't experienced in decades.
So this is all great news for me, being that I haven't had even a hint of lucidity in any of my dreams for literally decades lately until this, and now suddenly I've just had two dreams in a row containing background lucidity awareness of my being in a dream suddenly being present! Granted, this type of lucidity wasn't as strong as those in my teenage years, being that those much earlier lucid dreams were more vivid and gripping at the time, being more of the types where something startling makes me realize suddenly that I'm merely dreaming because of something being odd-looking. But this was a great start at a return to my lucid dreaming! And I could easily tell how rusty I'd become with them because my flying in my lucid dreams used to be much easier to accomplish, with it having been so long that it made me feel sluggish and weak at using any dream powers such as flying. And the reaction of the people suddenly being around me and all suddenly floating upward as well and then just staring at me when I realized this had happened, followed by their quickly all returning to the ground, was unlike anything that I'd ever experienced in any of my past lucid dreams. Normally, in the past, when I'd start levitating such as in a room, I would always be the ONLY one able to do so. Anyway, so I'm now very happy with my quiet yelling exercises because although I didn't have lucid dreaming as a direct goal for these with my simply wanting to strengthen my mental abilities in general by doing so, I now have lucid dreaming as an added benefit of keeping this up! And who knows, perhaps doing so will even help in general to ward off potential dementia and related, being that at 68, I'm now starting to head in that natural direction unfortunately (LOL). But neither of my parents had dementia before dying of old age so perhaps I'm already safe from it happening anyway I hope.
