The three men are different aspects of your own personality.

3 - the trinity. It is an active or a process number (something is going on in the psyche). The number three may symbolize vision(forward thinking), completeness, and fulfillment. Also, anything that may contribute to your personal fulfillment for example, the resolving of conflict between two opposing forces.

Red - Red is an active, affective color, full of passion and emotion. It may symbolize passion, luck, joy, happiness, energy, action, sexuality, revolution, warning, danger....but also hate, anger, sin, greed, irritability and will power. As the color of blood, red is also the symbol of life.
A softer red is a symbol of love, mercy and compassion.
Light red stands for warmth and affection.
When intense, red can also indicate hatred, sin, rage.
Dark red is a symbol of passion, energy, greed, and anger.

Smoking - almost always represents addictive patterns of some kind. This may deal with unhealthy eating patterns or even addictive relationships. In some case it means an addiction to a pattern of thinking, such as rage, abusive power, or the insistence that you are always right. Consider, what part of your life might be the stage for an addictive pattern, what has taken hold over you (buying lottery tickets, shopping etc.). Also it represents the risk for you if you continue doing so.

Alternately, if you are an ex-smoker, it is very common for to dream about smoking. This type of a dream could be called wish fulfillment or a compensatory dream. The smoker misses smoking. He can not smoke during the day, and therefore he smokes in his dreams. If you are dreaming about being surrounded by other people's smoke, you may be experiencing some confusion and anxiety in daily life or in regard to a particular situation. Smoke or smoking usually depletes people of energy and hampers ones ability to think clearly and act directly with the issues at hand.
