Anyone superstitious

I recently lost someone special to me 😭 on Wednesday. It has been hard but I’m coping with it. Today I saw a black butterfly which I never seen before and then right after I saw a white butterfly. Could it be a sign or some special meaning. Just asking because it was just random. The black butterfly was flying in the front of my yard when I noticed it and when I was about to go inside, the white butterfly was flying near my front door.
