Yes unusual dreams can be totally normal when you’re doing deep healing work. Your subconscious mind processes during your sleep and part of the processing can involve strange dreams. The subconscious mind works with metaphors so don’t worry if you have some disturbing dreams. Usually what is shown in the dream isn’t literal and is just a representation of feelings and events that the subconscious mind is processing.
If you are having recurring dreams or very disturbed dreams, keep a dream journal and write down what happened when you wake up in the morning. See if you can notice a theme to the dreams (pay attention to how you felt in the dreams more so than what actually happened in the dreams).
