Let's talk about dogs first. I dream that dogs are friends, neighbors, classmates and colleagues from the perspective of dream interpretation, symbolizing morality, self-restraint, self-demand and discipline or the superego mentioned by psychoanalytic psychology.
Finding your dog means that your friends will bring you good luck, although it is also accompanied by a little bad luck (I don't need to say what bad luck means? )
Let's start with the guitar in front. You were lovelorn (before) and always wanted to find a love, but what you found didn't meet your dream. (Judging from this, you are the one who was injured in the last love ...)
In fact, dream interpretation is to give you a comfort. If not, you can watch and play. It's boring if you're serious. Don't let dreams affect your life and thoughts during the day.
