was dark

If there is darkness in the dream, it means that the dreamer is facing difficulties and he cannot objectively observe and judge himself from a distance. Perhaps he should first analyze his own negative effects and eliminate them before he can gain light and clarity.
If the dreamer is surrounded by darkness in his dream and looks at others standing in the light, it may indicate that he is about to face a stage of frustration. If the situation is the opposite, it means that the dreamer has the knowledge and ability to help people around him improve their lives.
Darkness in a dream usually refers to a bad situation.
