I didnt believe in lucid dreaming until it happened to me randomly.
In the dream I was in a store and a kid was digging in the floor. I realized that it was a dream and told my wife in the dream. Everyone stopped moving for like 10 seconds and I woke up.
I did a bit of research after and found out that when you tell people in a lucid dream they're not real they will freeze or become violent.
Don't know how to do it again.
