Heaven is a place where there is no suffering and everyone is happy, so if you dream about heaven, you could be seeking relief from physical or emotional pain or from sadness in real life.
A dream about heaven can be a message that you need to be more optimistic about your future, or that you should have more faith in yourself or your loved ones.
You may dream about heaven when you are feeling that a situation in your life is hopeless. Your dream is telling you that you should not give up hope.
If you are under a large amount of stress in real life, visiting heaven in a dream can be a way of escaping from this stress when you sleep.
If religion or spirituality is becoming an important part of your life, heaven may be a common symbol in your dreams.
