Vertical
To dream of a vertical line or something that is vertical symbolises the spiritual realm and the supernatural.
Library
To dream that you are in a library signifies your search for knowledge and your hunger for ideas. You may be trying to seek out new meanings to life. You need to study and evaluate your situation before taking action. If the library is disorganized, then it suggests that too much information is coming at you at the same time. You are having difficulty sorting it all out.
Trash Compactor
To see or use a trash compactor suggest that you are in denial about some issue or problem. Alternatively, the dream means that you are looking at your problems from a different perspective. You are trying to look at things in a more acceptable or presentable way.
Death
To dream about the death of a loved one suggests that you are lacking a certain aspect or quality that the loved one embodies. Ask yourself what makes this person special or what you like about them. It is that very quality that you are lacking in your own relationship or circumstances. Alternatively, the dream indicates that whatever that person represents has no part in your own life anymore. In particular, to dream about the death of your living parents indicates that you are undergoing a significant change in your waking life. Your relationship with your parents has evolved into a new realm. If you dream about the death of a child, then it implies that you need to let go of your immaturity and start being more serious. As your child reaches certain milestones and grows into an adult, dreaming of their death may be symbolic of their own self-discovery, transition and transformation into a new stage of life.
