The meaning of Piñata in dream | Dream interpretation
Dreams of a piñata symbolize a celebration. Because a piñata usually involves a blindfold, this dream can symbolize that perhaps your desire is blind if you are lashing out to obtain something that you aren’t even sure you want or need. This could also mean that there are always goodies awaiting you, even if you can’t see them. See Blindfold.
If you saw a pinata in your dream, you may feel that happiness is hanging just out of your reach, especially if you tried and failed at opening it.
If you suceeded in smashing open the pinata, you will soon be happy - even if you don’t believe it at this second.
