I am not convinced that the dream told in the OP indicates that Obama is the anti Christ. Its just assumptions instead of a clear direct answer.

And also, i have dreamed of the anti christ. In that dream i was shown that the anti christ is the embodiement of everyone that is willfully blind with both eyes. Seeing is believing, and reality is belief. So people that want to be blind do that to avoid accepting the truth. And that is how they try to prevent God's Kingdom from manifesting.
