So to me, this is talking about ruminating about the past through meditation. Dark meditation. Dark meditation to me means he is seeing things through a distorted lens. Seeing things where he is condemning himself or blaming himself or through aggression turned inward. Not seeing himself as a good or worthy person. So because of this he gages his mind behind the wall. Think Pink Floyd. The guitar playing seems like the emotions. Into the rock - to means he is closing his mind or emotions to hide it from himself because it hurts so bad to feel that way. (the loneliness) Through walls of red dreams - to me means through his anger at himself. Then I think the meaning of dark meditation changes in the second part - to me it means that he starts to see the truth of himself being worthy of self love through those same walls of red dreams. It is a slight or subtle difference, but that is when the stream of light begins to flow. Into the meditation to find the cream seems to mean that there is good there and he is choosing to see it for what it is rather than through the distortion of self hatred or aggression turned inward.
