namccor, Sam could also try using paints / colors to express some of the feelings of the experience or try something like free associate writing. Even metaphor oatmeal can help, but I suggest that while trying to explain what happened Sam tries to relate anything he can come up with directly to himself and his life and mental state. Perhaps this way he can find the center of his distress within and dissolve it.

wishing Sam luck on his journey toward integration.
