It depends. Are you asking something along the lines: what does it mean to dream about your spell's intent And then have second thoughts... If that's the case and you are having thoughts, look at your spell. Remember everything you did during the spell. Remember why you did the spell. Was it done rashly, was it truly done for the reason you keep telling yourself, have you seen anything that shows it hasn't worked like it was supposed to, do you feel guilty? If any of these questions can be answered in a way that you don't like the idea of, maybe you shouldn't have done the spell. If you want, you could attempt a reversal spell. My hope is that this helps you.
Good luck in your endeavors!
