a few months ago i had a dream my old manager at work was crouched down in the dream he was looking at me and surrounding him was darkness and then i suddenly woke up can anyone interpret?
Most dreams are messages from the subconscious mind. You are just processing daily thoughts, feelings and events in the dream.
Darkness could mean many things - such as, he is in the dark about some issue or there were others around him who were keeping him in the dark, perhaps telling him deceitful things about you. Darkness could also be a symbol of someone who is not spiritual awakened and who makes many of his personal decisions in the dark.
I would assume that your relationship with this manager was not good at the time you guys parted ways because he wasn't looking at the whole picture or he was kept in the dark about the truth.
Perhaps you think of him as a "dark" or bad part of your life?
