Dreaming of a bier means you are fearing for a loss, and someone dear to you will no longer be a part of your life. All is not the end, as all things animate and inanimate works in cycles. A sense of loss will be replaced with a sense of gain as time passes by.
It can also represent defenselessness and vulnerability. To see oneself on the bier in a dream means that one will be hurt by another person who has strength and power over him or her.
Some possible causes for these dreams are feeling defenseless in the face of an aggressive or violent person in waking life. In other cases, the dreamer may feel powerless to save his or her livelihood from losing its ability to generate an income. It may also be brought on by excessive work overload or other responsibilities that are beyond one’s capacity to handle.
