Dream of

This dream has been happening to me since I started the school year. A lot of the times I doze off, I approach a situation in which there is a zombie apocalypse. However, it's always lucid for some reason and I control the outcome. Whenever I failed to survive and get cornered by zombies, I have the same dream reoccurring until I outlive that zombie apocalyse. Then the next dream is a different scenario but the same situation, I would be controlling my own actions in the dream but repeat it if I fail.
