Dream about a smiling horse is a signal for your tendency to keep you emotions and thoughts inside instead of expressing them. You need more discipline in your life. You are seeing things differently as you grow older and gain more experience. This dream is a symbol for a distribution of power. You are a non-conformist.
A smiling horse dream is a harbinger for respect and reverence. You are pondering a life-altering decision. You are looking for advice and direction in life. This dream points to your quick thinking ability and keen wit. Your conscious and subconscious are in an emotional conflict.
If you dreamt about a smiling horse:
There is a lot of talk going on today, and that is all it may remain if it is not starting off some kind of action. You want a certain romantic connection to move in a specific direction. Whilst the talking may set the scene, you need a more direct approach to make it work.
