Well, after day 17 my dreams got very vivid. Tonight my dream was very lucid, the longest dream I had and I almost got lucid. The beginning is not clear for me, I think I was at a police car or so, and a car crashed into a bridge and the police stopped the traffic. Then a location switch happened and I and some friends were at a school and we were 15 minutes late for sport lesson. So we went into the school and at that point, I noticed something isn't real. I only thought "I'm dreaming. Make a reality check", but a location switch again and no awareness anymore. Then we went thoght a forest to a railroad crossing. The lights were german and american, both were installed there. The barriers were open and some guy started to walk on the railroad crossing. Then the lights started flashing and the guy left the Xing. The crossing was somehow strange, because 5 or 6 barriers were on top of the other. After that again location switch and I were in a big hall. Some classmates were at a stand were games could be played. You had to pay €2 for one game and could throw a dice, but the appearance of the dice changed when I looked away and again. I didn't played it and then woke up. After 17 days my eyes are closed then and I don't move and make a rc first, but I was really awake and couldn't insert again. I'm very happy about my successes and hope I attain lucidity in next dreams.
