After about a month of dream recalling and reading stuff on lucid dreaming, I had my first LD just a while ago (around 11 AM, after WBTB - before going back to bed I was really motivated and used auto-suggestions to not forget to do a RC) .

It was a false awakening where I'm writing down my dreams like I usually do, but this time I do a reality check by pinching my nose. I can breathe!! I'm sooo happy. I do a RC a couple of times and it confirms that I'm dreaming, so I start flapping my arms so that I can fly. When that doesn't work, I start jumping on my bed so it might help in lifting off. That doesn't work either. Then I wake up. I'm really happy since this is my very first LD, but next time if my dreams aren't false awakenings then it would be harder for me to do a RC

I'm wondering why I can't fly?
