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.
