Gladys Herrera Sulca answered question 10/20/2009 I Always Wake Up At 3:00 AM. Is There Any Paranormal Or Scientific Explanation For This? It happens to me too, but I wake up with arms and legs pain for no reason! I am freaking out. It's not even because I want to pee or something, I just awaken. I open my eyes and then go back to sleep minutes later.
