When something is live it is full of perhaps unspent spiritual energy. Considering such energy may alter our perception of the life we live. If we consider that to live is to use energy effectively, any image in dreams that highlights this, constitutes a reminder. Live ammunition, for instance, suggests that care and control of danger is necessary. The implication that an animal or person in dreams is living suggests that it still exists. To dream of a dead relative as being alive suggests either their existence in memory or within the spiritual dimension, depending on our beliefs.
