I had a lucid dream about six months ago and have been obsessed with the topic ever since. After researching a bit, I found exercises and techniques that can induce lucid dreaming. I can now "control" some of my dreams. Anyone else doing this?
Although I wouldn't consider myself practiced in lucid dreaming, I do believe that I have been in such a state prior. You should look into 'astral projection', which is another theory people find to be closely related. My girlfriend is on Reddit a lot and has done much reading up and sharing on both with me, so it's a familiar topic, at the least!
