Please tell me what are signs of lucid dreaming?

Rational dreaming: Lucid dreaming involves some type of rational input into the dream. That input could simply be our reassuring ourselves that we are safe. For example, saying to oneself, in the dream, that it is a dream. The input could be more elaborate with our rational mind coming up with a solution to a problem. Some people can influence their dreams by programming them through self-talk before falling asleep.
