Lucid dream yes I have heard of this
and also had them
its a funny thing but hard to control since the transfer from dreaming to lucid dreaming occurs "I think"just before u start to wake up because then u realize ur dreaming and can't stay asleep anymore now I had this lucid dream was when I was falling down a cliff I`m sure more of u have had this dream cause its a very common dream the whole falling things
well normally before u hit the ground u wake up in your bed and have this wicked feeling this time I kept on dreaming and Hit the ground VERY HARD and it had hurt me
it was really weird hitting the ground instead of waking up
so I got on my feet and walked out of the canyon I was in and came in some kind of theme park in which I could let myself get killed in a 101 ways
which I did and that was kinda a cool experience lol
and yes its true that smoking weed pretty much stops the dreaming
I noticed that myself when I quit for about 2 months and started to have dreams each night again and very realistic and fun dreams
and some of those were lucid
but I still wanna train to get more of those dreams
but I fear that when I become good at this. u start creating a second reality "sort of" and it will be harder for me to make the difference between those
I have a friend who can do lucid dreaming whenever he wants
and he just lives on in his dreams as he does when he's awake
I dont even wanna know the juicy parts lol
