I have been waking up from dreams (specially nightmares) for a long time, even before I find out about lucidity in dreams. I have now become lucid 2 times and in the last one I tryed to wake up because I had a meeting in the morning (I had already awaked with my alarm but I slept again ) so when I tryed I had to make a big effort and false awakned 2 times before I managed to be really awakened.

This may sound a bit strange but does anyone have any tips on how to wake up?
