The retreat, defeat - a blow from his relatives, the risk of which is not anticipated.
A spiritual retreat is a place that allows us an environment and ambience in which to meditate and contemplate. To dream of such a place suggests we have need of peace and quiet. When we dream of retreating from something we may need to decide whether it is a forced withdrawal or a strategic move. If the former then we may be under pressure, if the latter then we must formulate new plans. When in dreams we are conscious of retreating from a previously held position this may be because we need to reassess our resources.
To a public shame.
