This night I definitely had a lucid dream. I mean I had dreams before in which I was kind of half-lucid (knowing that I can control the dream but not knowing it is a lucid dream). I tried with different stuff for approximately 1 month now and it didn't work, but this night I awoke from a nightmare after 5 hours of sleep. In the nightmare I was in my room and everything was dark. Somehow I knew there was a killer in my house which wanted to assassinate me and then, the door to my room opened and the assassin ran in, with a saber. I was terrified, but woke up before he slew me. Awake, shocked I realized it was a nightmare (but was still terrified, because I lay in my bed in my room in which a few seconds ago was the killer). I switched on TV, watched for about 45 minutes, got back to bed and fell asleep again.
Again I dreamt vividly. The funny thing is, I was still in my room and there was this nightmare-atmosphere. But something was different, because suddenly in front of my bed there was a black flat screen computer monitor, which I have never seen before. I examined it at close range and thought about why that thing was in my room, but didn't realize I was again dreaming. I stood up and walked around the room, suddenly a strange person stood at my window leading to my small terrace and I wanted him out of there. I somehow knew I could shoot him out of my room by sheer willpower, so I threw a force ball of some kind at him and he flew out on the terrace. I stepped out, to finish him off (don't know where that brutality comes from normally I'm very peaceful) but he vanished before I did anything, and then FINALLY it dawned to me that what I did could only be possible in a dream. So I checked everything, reality checks and verified the dream. Then I checked my senses, hear, touch, see and I must say the one that was most clear of all was hearing. Touching was also quite real, but the environment was a little (only a little) bit blurry. Perhaps that is because I am short-sighted in the waking world. However, I touched several things, astonished, then I tried to fly, and I did. I flew into my school courtyard and saw all the people, talked to them and examined my first lucid dream. Then, I shouted several times "This is a lucid dream", as a kind of remembrance and proof for me in the waking world, that I really did dream lucid. I wouldn't have expected my first lucid dream to occur after a nightmare, but well, it did. The dream was much more complex then that, of course, and I won't post everything here because this is already way too long. I hope you don't mind, otherwise sorry for the long reading effort.
