I had a lucid dream last night and tried to turn my dog into a furry
Why did you want to turn your dog into a furry during your dream?
It was only a dream not real life.
It's perfectly acceptable to have dreams that do not make logical sense. Your dog is already an animal so it isn't possible to turn your dog into a furry. Sometimes dreams are just dreams and do not have any deeper meanings behind them.
It's my dream. I'll turn my dog into a furry.
As long as you are not acting out this fantasy on your pet you should ignore it. It is wrong to be sexually attracted to an animal.
