Two things stand out for me:
1) What has this to do with Lucid Dreaming? Those were the only references to lucidity in the whole shebang. It just reads like a normal chaotic non-lucid dream... no mention of getting lucid, the how and when..
2) You wrote: "..I was in my school heading for lunch.."
Now.. you claim that you are 20, right? So why didn't you say "my old school"? Or are you a 20-year-old who is still at school?
