Laughing 
To dream of laughing may indicate a buildup of stress or tension.
Seeing or hearing many people laughing is a message to give yourself a break and be a little more playful in your waking life.
Someone laughing at you implies social anxiety and the need to be mentally kinder to yourself.
Joke
To dream that you are telling a joke implies that no one is taking your word or actions seriously. This leaves you feeling frustrated. On the other hand, it is possible that you are purposely not taking an issue seriously.
To hear a joke in your dream denotes something useless and outrageous. This may also mean a respite from chaos and problems that has been bothering you for some time.
