Not exactly

The events depicted in the dream (i.e. blowing your son) have only symbolic meaning in reality. To give you an idea of how fucked up the interpretations are, take a look at this passage:

But the actual locations of the dreams also contribute a great deal to the way in which dreams come true. For example, a man dreamt that he was crucified. Crucifixion dreams signify honor and wealth--honor because the crucified person is in a very high position and wealth, because he provides food for many birds of prey.
