What is the meaning of this scary dream?

There are various facets of the dream narrated. So, before answering the question proper, we need to understand the process of dreams as far as the interpretation part is concerned. The dreams are actually a fine tuned process of perceived actions of our mind and the sub conscious. The mind is a store house of our feelings, gathered or gained self experiences and ideas present in our subconscious mind. Whenever, we are in a situation about which we are not able to take instant decision, our mind comes into action .Based on the situation, the mind collects data from our so called 'store house' and projects it in the form of dream. Seeing someone dead in this case represents an action of the past which has been against the wishes/ family teachings. The act is of concern, hence everyone in the dream is rude. Therefore need is to take corrective action earliest without loss of time. Things will improve. BOL(Best of Luck ).
