Example: A man dreamed of seeing possums in his backyard. In waking life his father had promised him $200,000 when a home was sold so he could start a new life with a new business that was taking off. The father promised this because the son paid off all the mortgages and property taxes for 10 years.
He noticed his father doing everything he could to avoid paying the money with delays and excuses because he never really wanted to pay his son at all. The man felt his father was jealous of his new business allowing him have a life that didn't require paying all his father's bills anymore. The father was planing on threatening to retire as soon as his new business took off so he could never stop using him.
Example: A woman dreamed of avoiding running over a possum with her car. In waking life she had decided to move on with her life from old friendships that had deteriorated and was having trouble telling the people to their face that she didn't like them anymore.
