Hey yaya!
Everybody is different! They express their lucidity in a different way that shouldnt bother you. Even if you dont have a good emagination you can still pull out some good and interesting lucid dreams. Its all up to you and how you feel things.
You can try setting your intentions for a sertain lucid dream or lets say look at a tropical island for instance and set your intentions for that typical island.
Anyway I wish you good luck in your next lucid expirience!
