I have had a lucid dream exactly one (1) time and I think I fucked it up.
I dreamed I was driving past my old college and I went “Wait this is a dream! I can do whatever I want!” and I immediately swerved into oncoming traffic and right before I hit a truck I thought “Boy I hope this is a dream or this is going to really hurt”
And then I woke up.
I have not had a lucid dream since.
