What does it mean when you have a dream about hell?

The meaning of any dream image depends on the beliefs, experiences and traditions of the person having the dream. If the dreamer comes from a literalistic Christian tradition, a dream about Hell could have deep religious significance. A pious believer might feel called to preach about the threat of punishment and the need for salvation (as described below.) A different person might dream about Hell because of feelings of guilt and remorse over some behavior. Yet another person might need to escape from an abusive relationship, and a dream about Hell could be the mind's way of alerting that person to get out of that "hellish" situation. See attached link for more information on how dreams use symbolism.

when you dream about hell probably God wants you to see hell and to feel how it is so you can prevent from going there and probably so you can tell people and they can be saved from that place.
