Welcome Stefaans! As you may have gathered, some of the best lucid dreamers seem to have dealt with strong nightmares. I don't count myself in that category but I did also discover lucid dreams for dealing with nightmares when I was young and after defeating the nightmare went on to some adventures but then forgot about dreaming (for the most part) not long after, until more recently...many years later. I am sure we can also learn things from you!
