This dream is connected closely to water. If in your dream there is no water in the dam then you may encounter bad luck for a short period of time, it is always best to take these things with a pinch of salt and that things are likely to improve in the future. Basically, if you take the literal meaning of this dream "to be damed" then this is likely to explain things.
If however, your dream contains water and the dam has burst in someway then you need to develop some resistence to a situation in your monetary affairs.
Also, see the meaning of water for more clarification. If you are looking at a dam from above, and not actually in the dam then this shows that you can deal with anything life throws at you, if however you are in the water or in an empty dam this represents that it is time to think about what things in your life are making you feel tired as it is time for recouperation and rest.
