I had a dream my I was baking steaks and 1 fish, when I checked on it the fish was alive so I decided to cut his head off so he would?

not suffer and it struggled, half way through it turned into a black and white kitten but it was too late to stop and it live. I was upset. I have had dreams of killing kittens before. I love cats and have 2.. what can this mean?? Thank you in advance.
