Hello, finally i had my first LD! you can read it with link below
(July 23, 2014) First Lucid Dream! DILD - Dream Journals - Lucid Dreaming - Dream Views

I have a few questions though,

I felt as though I was losing my grip on the dream when i got excited, became harder to move for a moment, i tried to spin and i couldnt, and as though the dream was almost becoming non lucid again but i kept up with holding it. Can you slip back into non lucidity without realizing it?

Do some dreams feel as though your loosing your grip on control?
