What dose this mean?

[Marrelito]

Hi everyone, i recently registered here, seems like a good forum to talk about dreams and learning more about dreaming. I was wondering if anyone knew what it meant if you say to yourself (in a dream) "I am dreaming right now" and then when i realized i was dreaming, i started to look for details on a wall or the ground. obviously i was liquid dreaming, but then i notice i could just wake up whenever i wanted, just telling myself (in a dream) to, "wake up now" and i instantly do so. I've been able to do this a few times and, i can remember one scenario i was just falling down and i didn't want to know the end of it so i told myself to wake up and i did. And sometimes i just wanted to wake up to be in our present world. maybe someone know more and could help me understand why these things happens in a dream.
