Speaking from experience, lucid dreaming is actually very real.
The basic premise on how it works is for you being able to realize you are dreaming while in your dream, and then take control of it. If i recall the steps to this were
Jumping in your dream, the physics is different so you float usually or theres a slow mo effect and I think something about looking at the time pass on your watch.
You are supposed to do these checks in real life till it becomes a habit to check when you're dreaming too.
Once you realise you're in your dream world, you can literally dream of anything.
When I was like 18 I had a huge crush on Catherine Zeta Jones.
So when I realised I was dreaming, I made myself open my door and have her appear loving behind it. Not going to go into anymore details but that was the most amazing dream I have had in my life and till this day I still remember it because it felt SO REAL!!!
Unfortunately after that, I tried repeating it but she was never there again (dunno what i did wrong she just never appeared) and after that I was too lazy to read up how to fix it so that was the end of my lucid dreaming days and I never bothered again as my mission for lucid dreaming was accomplished heheheheeeeeeeee
