I don't remember my first lucid dream, because I was a little kid at that time, but I do remember one of my dreams.
I was dreaming if I have lived back in Medieval times, staying at a castle. I was one of the guards going about the castle to make sure no trespassers would come in and then I went outside where leaves were on the ground and the trees were thick around the castle (it was fall in my dream). I came up to a stream, the stream was deep but I saw a sword in the water. I put my hands in the water and it actually felt like real water, it was cool and wet, but I reached for the sword in the water and I was able pull it out. At that time, before getting the chance to read what was on the sword, I was awaken by my mother telling me to get ready for school.
After coming back home from High School, I went to sleep again hoping to return to that dream, but I couldn't get it back :(
