Clowns are most usually masked. Seeing a clown in your dreams is a reflection of your mental / emotional state. If you see a happy clown this could show a light hearted child like nature in yourself. On the other hand, a sad clown could be showing you that you have some emotions you need to work through. An angry clown could be hidden fears coming to the surface.
If you have a phobia of clowns then regardless of happy, sad, mad, you will have an adverse reaction to the dream. Seeing a clown or clowns in your dream when you are fearful of clowns could be a sign that someone is in your life or about to enter your life who cannot be trusted! The idea behind clown dreams is to “unmask” the emotions within yourself or pay heed to your gut instinct when dealing with others. Once you uncover the face behind the mask you will have more clarity on which direction to take.
A fun, fool hearty clown in your dream may signify that you need to be more careful in your day to day life and take more time in processing thoughts and feelings before speaking or taking action. This can also be a sign that someone else in your life is about to make a mistake that you could aid them in or perhaps stay away from them as it could bring you some form of harm. On the other hand it can also mean that you are about to embark upon a fun time where troubles are cast aside.
In any dream it is important to not just look at the large significant things that pop right out at you or simply google a key word. This cannot interpret your dream as a whole and are only a starting place to truly understanding your dreams.
