Darkness 
To dream that darkness comes upon you indicates defeat in a project that you might try. Darkness is symbolic of incomprehension, the unconscious, malice, death, and concerns about the unknown. If the sun pierces the darkness, you will be able to defeat the obstacles in your way. If you feel confident in the darkness, then you don't need to understand everything about things around you. The phrase 'ignorance is bliss' fits here.
To dream that you can't find someone in the dark suggests that your anger needs to be reined in and controlled. You allow your feelings to get the best of you.
To dream that you are lost in the darkness indicates a sense of despair, sadness, or uncertainty.
To dream that you are groping in the darkness signifies that you do not have enough knowledge about a particular topic to form a valid decision. Dig into the topic and don't make snap decisions.
Hell
Many people are brought up to believe that hell is the ultimate punishment and a certain end for 'bad people.'
To dream of hell is usually accompanied by magnified feelings of fear and uneasiness. One interpretation of such a dream is that you're having endless problems
Another is that you no longer have control over your life. A burning hell can signify the inescapable old feelings of guilt and shame, as if you're punishing yourself. You need to get over these emotions and find ways to solve your issues.
Shadows
To dream of seeing your own shadow represents a hidden part of your personality or character that you are unaware of. These attributes may not necessarily be derogatory, but perhaps you are reluctant to reveal them to others out of fear of rejection or embarrassment.
To see a shadowy figure in your dream indicates that there are traits you possess but don't fully realize or comprehend. It can also represent someone who is immature, naive, and impressionable.
Death (Dead)
Dreaming about death is very common. Death is a natural part of our lives and affects each one of us that it is no surprise to be a part of our dreams. Dreams are sometimes a place in which our minds explore concepts or situations that we fear, or are unable to process with our conscious selves. A recent death in the family is likely to inspire dreams of the lost loved one, particularly if there are still unresolved conflicts between you and the one you've lost.
To encounter someone who has died in one of your dreams is an attempt to resolve conflicts which you were unable to deal with while the person was alive. They may also be appearing to you in a dream because you are missing something about them. For example, you may have felt very close to your grandfather before he died. Perhaps you used to go to him for advice and guidance. When you undergo stress in your daily life, your mind might remember how much consolation and assistance he gave you and bring him back in a dream. Listen carefully to any advice given to you by a ghost in a dream. These words are what your mind imagines that loved one would have said. The dream is trying to give you the consolation that you need. This is a natural part of the grieving process.
It is also common to feel that you are dead in a dream. You look around and understand that the world you are seeing does not meet your expectations of reality. A dream, of course, is not reality but sometimes instead of realizing that this is a dream, your mind jumps to the conclusion that you are dead and seeing the afterlife.
You may dream that you are dead and watching your friends and family grieve for you, and continuing their lives. These dreams are also related to the fact that your mind is confused about why it cannot control your body movement since you are actually motionless sleeping in your bed. This can also be a way for you to examine your feelings of loneliness or uselessness if you are struggling with feelings of inadequacy in your waking life.
