3 times in the last week I have become Lucid in my dreams. But each time I perform a reality check and then begin to experience my Lucid Dream it ends! Im not sure what happens, I dont remember if I wake up or continue dreaming or what. My memory of the dream just ends. I dont remember false wakenings and I dont remember losing Lucidity and continuing to dream, it just stops. Its annoying. Is this common at all?
