I think the idea is to build a habit of checking, so you don’t even need to have that “hold on, am I dreaming?” moment. You just habitually do that thing you always do, and then “oh it seems I’m dreaming. I didn’t notice”
I see. Will avoid, then. I don’t like lucid dreaming, always wake up right away. Whenever I notice I’m dreaming it becomes hard not to notice that I’m in my bed and that I can feel my covers and by that point it’s all over, so whenever I notice I’m dreaming I just cut the crap and open my eyes for a couple of seconds to wake myself up and then close them again so I can get back to proper sleep.
