I Need The Help Of All This Lucid Dreamers Here

Well 3 Questions1-Is Lucid Dreaming really that great,because I've heard a lot of lucid dreamers say that its a curse and they would rather dream normally since it gives them headaches all the time or something along those lines and apparently makes them very tired as if they didn't sleep at all2-What exactly can you do in a Lucid Dream,do you have FULL control over the dream and can change your environment for example and create people or change your form or something like that3-So how DO you Lucid Dream,ill admit I'm fairly new to the subreddit but I haven't seen any "tutorial-like" posts around,and I've always wanted to experience a Lucid Dream once at leastTL;DR:
1-Is Lucid Dreaming really that great?
2-What EXACTLY can you do in a Lucid Dream?
3-How do you Lucid Dream?

Thanks a lot,one more thing that just makes Lucid Dreaming a big nope for me is the possibility of developing sleep paralysis which just terrifies me

Maybe...but then there's the headaches thing and they say they're tired because their brain was "working" all night as in controlling the dream,also is sleep paralysis a possibility if i try to lucid dream

Ok thanks a lot man,i really appreciate the help,any useful ways for #3

Well how can I conquer and defeat the sleep paralysis and enter a lucid dream instead (idk if its even explainable)

I meant that the brain is "working" more than usual,since you control and think of everything around you

So wait,are lucid dreams intentional,or can they be intentional or do they just happen randomly

The thing is,sleep paralysis just terrifies me so i might not try to lucid dream if ill have to go through SP,all the movies and documentaries just make it seem terrifying as shit

Thanks a lot

Oh wow....ill try and give it a chance but i hope its that easy

Ok thanks

Yeah thanks

Thanks so much
