To dream of heaven represents perfect happiness, bliss, or transcendence. A state of mind or situation where everything is working out. Feeling that everything you want is happening. Feelings about life working perfectly or feeling very happy to experience a moment of extreme luck. Situations in your life where you feel an exceptional amount of support from other people that may be unusual for you. Feelings of paradise or that a situations "feels like heaven." Preoccupation with escaping a depressing or banal life. Preoccupation with restoring optimism and hope to your life.
Negatively, dreaming about heaven may reflect too much wishful thinking or desire for a perfect outcome that may be unrealistic. Expecting too much from people to make your life perfect. Expecting strangers you just met to perfectly fix your problems. Problems with accepting that the fact that you need to deal with your problems on your own. Difficulties accepting the hard reality of a situation. Too much confidence in strangers solving your problems. Naively believing that perfect happiness is possible.
To dream of not being allowed into heaven may represent a situation in waking life that prevents you from achieving total happiness. Feeling denied from happiness. Anxiety or jealousy that you weren't perfect enough in some way.
Dreams of heaven may occur for people who are very religious and experiencing anxiety about God thinking they are a good person when they die.
Dreams of heaven are also common to people who may have had a very hard life (disabilities, bad family, bad luck) and believe that supportive people they meet for the first time are going to solve their problems.
Example: A deaf woman with severe disabilities dreamed of being in heaven. In waking life she had met someone off the internet and then began to believe that they might help her to fix some of her problems when nobody else ever wanted to help her. The heaven symbolism may have reflected her naive belief that the new person she met off the internet would make her life perfect as deaf people tend to have issues with trusting people.
