hi all i am a 15 years old guy who first attempted to have a lucid dream last night , after i had the best dream of my life and wondered if i could have done it again

I've found this site and i attempted to have reality checks during the dream.
I was surprised in the morning...i remembered 3 dreams!
THat never happened to me...and i was lucid too for a bit...and for some kind of reason i controlled it. Well not the whole dream just myself...a guy was trying to beat me but he couldn't hit me cause i imagined to become Invisible...lol...he passed through me.Then i punched him

For some reason i don't know i lost the Lucidity.

Hope to improve this technique
