My first "lucid" dream happened when I was 5.My mother had kept away some toys she found dangerous,the same night I dreamed like I was floating in a stop-motion sort of way from my bed to the kitchen,and found those toys.The next day I found (awake) the toys in the same spot,I guess I must had seen it but forgot it,but the dream was quite lucid.
After,this year,I was dreaming I was at my old school and was 10.I was so excited to be 10 years old again,I was jumping to the bathroom,everything was just like it were in real life.Then,I looked at myself in the mirror,and I could see my reflection perfectly,but then it got blurry and I lost conscience in the dream.
Those are my only times of being lucid in a dream,although some dreams I remember so well it was almost like a true memory.
