An addiction in a dream can represent an addiction in waking life.
Dreaming that you are suffering from an addiction can mean that you are behaving in a habitual, automatic way, without planning your actions or thinking about their consequences.
Your dream is telling you to pay more attention to what you are doing and to make more of an effort to think before you act.
If you dream that someone else is suffering from an addiction, you could feel that they are not considering the consequences of their behavior in waking life.
A dream that you are trying to fight an addiction can mean that you feel you have lost control over a situation in waking life, and that you are trying to regain control.
If you dream that you are addicted to something, you could be suffering from an addiction or an obsession in your waking life. Your sleeping mind is telling you something that your waking mind refuses to acknowledge.
This does not necessarily have to be a physical addiction, such as an addiction to drugs or alcohol, or to overeating, or another type of well-known addiction, such as a gambling addiction or an addiction to spending money. An addiction dream could be telling you that you are spending too much time thinking about an issue or about another person, and it is time to either confront the problem or person head on or move on and focus your thoughts on something else.
If you do drink alcohol, gamble, take drugs, or sometimes overeat or overspend, an addiction dream could be telling you that you are starting to lose control when you engage in these activities. Take care.
On the other hand, if you hardly ever engage in any of these vices, the dream could be reflecting a desire to let loose a little and enjoy some of these activities, as well as a fear of what will happen if you do.
