(Hanging) If one strangles himself with his own hands, or if he hangs himself with a rope which he attaches to the ceiling in a dream, it means that he is sufferings from depression, distress, or sorrow.

Dreaming of gas, denotes you will entertain harmful opinions of others, which will cause you to deal with them unjustly, and you will suffer consequent remorse.

To light it, you will easily find a way out of oppressive ill fortune….
