It is always nice to have another natural lucid dreamer. I too have had LDs since I was a kid. For the longest time I thought everyone knew when they were dreaming. Since getting more interested in it I've discovered that the possibilities with lucid dreaming is almost limitless!

A lot of people struggle with their dream ending when they try to control the dream at first. I suggest before you do anything fancy take a few moments to look around and just notice how clear and vivid the dream is. I call this "stabilizing." After this the dream should be much more stable when you pull out your tricks!

If you have any questions, feel free to ask!
