When I said I used to practice lucid dreaming, I didn't mean drinking herbal tea, listening to music and all that shit. For me it was just a matter of questioning, several times a day, whether you're awake or dreaming. It may sound stupid, but it's about getting your mind in the habit of doing these reality checks. If you stop what you're doing, a few times a day, and really analyse your surroundings, you'll start to do it in dreams. For example, look at a clock and check the time. Look away, and check it again. Often in dreams, our minds mess with things like that. It's these moments when we're suddenly like, "Shit, this is a dream!".
I had a pretty weird one the other week. I was at a car park, and some guy was holding someone hostage. He was threatening me.. when suddenly I became lucid. I said to him, 'you're forgetting something. This is just a dream'. Then I pulled out a gun and shot myself in the head to wake myself up. Pretty messed up.
