I have Lucid dreaming since as long as I can remember. Because of that, sleeping is like playing game VR. I can control the story but I can't control what I will dream. Sometimes it zombie apocalypse, sometimes my own memory and sometimes learning how to fly, which is really tiring dream. Apparently I can't fly flapping my wings directly, I need to fly like an eagle and trust me, running and flying isnt a fun thing in dream since you will be tired when you wake up.
Btw, I am not that person who is very wild sleeper. I mostly like mummy, same position wake up and sleep. Barely move. Even with aggressive fighting dream.
I also can't dream when I super tired. The more tired I am, the more harder to dream.
