Hey Hukif! I have been inactive for a couple years but I still use your technique and it works great. I hardly ever have to do a nose plug RC to realize I'm dreaming I just sort of know. It only happens occasionally because I haven't been disciplined with my awareness or dream journaling but It shouldn't take long to get back at it.

Your technique even saved me from a night terror one time, something that hardly ever happens to me. I woke up and saw a ghost girl staring right at me completely transparent. It was completely convincing and completely terrifying but because I could tell something was just a bit to floaty about my body I knew it wasn't real and didn't freak the heck out. Instead I got to marvel at the hallucination as she faded away. If I had to plug my nose before I knew it was fake I would have definitely shit my pants!

Anyways, back when I was more active, I did notice an increase in my dream recall after I got good at gravity RC. I also got better awareness while sleeping but not dreaming which makes it easier to transition into a lucid dream!
