So I had a lucid dream like 3 years ago but then I had no idea what it was and I couldn't control it well, now I have been trying for several months and yesterday night I went to sleep at 12AM, I woke up at 2:30AM and I saw a dream and remembered (is this normal btw? I thought you had to wait more hours usually to see a dream but whatever it doesn't matter I guess)

So I went and watched a movie for around 40 mins and went to sleep again, tried to WBTB but it didn't work, I just fell asleep normally, still remember seeing either several dreams or one/two very long ones. Then I woke up in the middle of the night and I tried to DIELD, it didn't work either, but I saw another dream, in the end of this I was downtown trying to go back home but I kept seeing things that didn't make sense so I was like
"Am I dreaming? Yes." Then I open my eyes!
I think this already happened twice, what do I do to not end the dream and actually experience lucid dreaming for more than a mere second?
