Well well well I actually succeeded in lucid dreaming this morning
I felt a strong ringing between my ears and focusing on it intensively so much that I was crisping my face, when I felt I reached some kind of peak I would open my eyes into the dream.
Firstly I got up of my bed and looked into the mirror and started doing magic. I would generated sparks of light on top of my hand and also generate electricity from one hand to another. While doing this I saw three times a dark silhouette from outside (from the mirror you can view the window in the back) and then I tried to.. shoot them lighting bolts to chase them away, which didn't really work as planned because to channel it I had to concentrate a lot but when I did so they would vanish. Also two of them had yellow eyes. Then a group of people came into my room and started bringing together every books and every things I had wrote. I asked them if they were of the Orion group and a man answered no. I asked him what was the name of their group and he said they didn't like names. I asked him if they knew me and he said no and that was why they were here. I tried following them but lost focus and everything became dark. So I did the process again and went back into the dream, they weren't there anymore so I started going around and found my sister. We spoke and bit and went outside where I saw again those people I had first seen. I told my sister that I knew them, and she said that here there was no one I could truely know. A lot of noise came from the real world and broke my trance so it ended that way.
About the cannabis part, it could apply to me since I'm a regular smoker, but I don't recall having a better ability with dream when I used to not smoke.
Also I didn't say this but I'm really no good at visualizing, in fact some time ago while doing of trip of magic mushroom I expended my mind to the possibility of visualizing which is now really weak but still something I can grasp a bit. Prior to that visualizing was completely something out of my reach and unkown to me despites a lot and a lot of hours of trying and meditation to succeed without any results.
