My husband believes he was Charles Chaplin in his past life ?

He may have a past life life connection with Charlie Chaplin, whether he actually was him or not. He can use this feeling to better understand himself and his purpose in this life now. It may be interesting to explore what it is he is drawn to in this regard and how he can use this knowledge to enhance his life now. This could be fun for you both, if you would like to participate in the exploration. A spiritual counselor, hypnotherapist, or mediation could be beneficial for this. You do not have to believe what he believes, but you can be supportive of each others interests. Best Wishes to Both of You.
