Moon conjunct with Ketu in a birth chart means that the native has a strong sense of intuition but becomes a difficult-to-understand personality, for you never know what he/she is up to. If your natal chart has such a conjunction, it would be in your best interest to give enough thought before undertaking a task, else, you may get upset when you will struggle to process on the commitments. The good thing is that you will always learn from your mistakes and try to mitigate the negativity surrounding you.
