I want to interpret dreams. I dreamed that cat shit was on my floor.

Then you should be careful recently, there may be some unpleasant things.

But don't care too much about yourself.

There are two possibilities for dreaming. First, you think about it all day and dream at night. Second, you don't sleep well. Try some foods that help you sleep. Third, don't be superstitious. Curiosity kills cats. Superstition will kill you.
