What are lucid dream dreams about?

so this morning i had a dream in which the moment i opened my eyes there was a demon standing on the left side of my bed . i thought i had woken up from the dream but it was just a false awakening. i wasn't scared but i couldn't move my body just like sleep paralysis but it was a dream. for some reason i still remember it clearly happening and i know it was a dream but still couldn't become fully lucid . i asked the demon why can't i move my body but he didn't utter a word. i just prayed to god and believed in myself that i can move my body and guess what i was able to rise up from my bed. i just went to a room nearby and the demon followed me. he said to me that he knows what i am thinking right now so i challenged him to read my mind and the next moment itself he started saying all the things that i was thinking at that time. i then just realised that this can't be real and when i was just about to become lucid the alarm woke me up.

Last night I had a dream where there was 2 moons one smaller that got stuck with earth, and the normal one. For some reason the second moon was causing problems so the US Government came up with a plan to get rid of the smaller one, how? by nuking it. They started their plan the next morning (In the dream) and basically blew it to bits but one of them put a few nukes on the REAL one and mountain sized pieces started ripping through the ozone and crashed down and somehow, I survived.
The aftermath was the world becoming swiss cheese and I was the only human left alive.
It was a weird experience and I kind of just blacked out and then appeared under debris. I also became lucid for a little when I guess my parents were waking me up because I heard a voice in the sky saying "Its time to get up" but what felt like 5 seconds I was awake.

It started with me at a crossroad, I tried to make cars collapse using telekinesis after finding out I was dreaming. Nothing worked. The strangest thing was that I could use my imagination, visualize things in my head, and then come back to the dream. That's how "stable" it was.

At one point, I encountered a man who wore a black jacket, and had thin black hair. He told me this dream was real.

I sighted heavily. "This can't be real!", I let out.

"Oh really? Well how about I prove it to you?" the man said with a grin.

"I will translate any given word or sentence to French, I assume you don't know any French... You can check Google Translate to see if it's correct when you wake up.", the man added.

I started thinking. What could be a real good torture test here?

"Hmm, I have been to France many times..." I said. "I'm afraid I might've subconsciously seen the word, and it's translation already."

And then I had a grand idea: "What if I translate a sentence that I never had to use IRL in France?!", I thought.

"Ok...", I turned to the man with a smirk. "Translate: I am dreaming".

The man said something back with a French accent. I don't remember the exact word anymore as I really didn't know how to write it. But it was really short.

"Wait that short? There's no way that's the French translation."

"Oh, I'm sure it is, you can check later when you wake up."

"Can you say it again? I really want to remember it clearly..."

The man said it again, it was once again audible but impossible to write down in letters for someone that doesn't speak French (and perhaps dreaming might have something to do with it).

"I'm afraid I can't remember that too clearly", I said, worried but at the same time not willing to let this chance go.

"Just type the English sentence in Google Translate and see if it sounds the same, that should be enough.", the man said very confidently.

After I woke up, you can already imagine the first thing I did. I opened Google Translate (https://translate.google.nl/?sl=en&tl=fr&text=I%20am%20dreaming&op=translate) immediately after waking up as to avoid forgetting any more than I had to. And indeed the translated sentence sounded exactly the same. Creepy...

My dad told me if I asked either of these questions, something really creepy would happen, and just so happened a few days later I had a lucid dream and remmembered to ask this, I was dreaming with 3 people that i knew: My mom, My dad, and my Grandma (Just for context). When I asked "What time is it?" Suddenly everyone stared at me, my vision started to get darker and shaky, My mom turned completelly black, her eyes turned red and she Glided extremelly fast towards me and I woke up

I can randomly start lucid dreaming but I can't control when it happens. I know some of you have control of it and I was curious how you've all trained yourself to lucid when you want to. What's your method?
