Started attempting to become lucid about six months ago. I just had my fourth lucid dream. But the first that I was able to stay in the dream. When I realized I was dreaming after a reality check, I felt that I was melting. In my previous ld's, my attempts at staying by feeling my arm or some other sensation didn't work, This time, I started spinning. It felt like I was spinning in slow motion, but when it stopped, I was still dreaming, but in another setting. Though, I think I lost lucidity because after I woke up, I realized I was just walking around and doing things like it was just normal reality. I wouldn't even have woken up if someone didn't knock on my door and woke me up. I think. Any suggestions would be helpful. Thanks.
