Sup guys

I was just wondering cuz isn't Alcohol supposed to decrease chances to get a lucid dream. But it's the third time now. although i don't drink that much only a couple of beers.Besides I usually don't have lucid dreams since i do not deal with lucid dreaming that much. btw all of them were suddenly induced like i just knew that i am dreaming.

so my question is if this is usual and why does it still work.
