Psychology Today discusses reality testing, mnemonic induction of lucid dreams, and wake back to bed.

The topic of lucid dreaming tends to exist somewhat on the fringes of sleep psychology, but advocates believe that by becoming more engaged in your dreams, you will sleep better and be more creative in your waking life. University of Adelaide (Australia) psychologist Denholm Aspy and colleagues (2017) note that anecdotal reports of the phenomenon date back 2000 years.
