Lucid dreaming may help treat PTSD. VR can make that happen.

Lucid dreaming is more than just self awareness. People who lucid dream gain memories of what happened earlier in the dream, the ability to manipulate their environment, control their own actions, and marvel at how strange their dream worlds are. Psychologists compare it to a fully immersive virtual reality inside our own heads, which we have the ability to program and reprogram. “You plug into your extended self,” says Benjamin Baird, a cognitive neuroscientist at the University of Wisconsin, Madison.
