2. Dreaming of a friend falling from a building: dreaming of falling from a building means that you are facing difficulties, which may refer to the same thing as the danger above.
Based on the above, I guess you didn't have a smooth life some time ago, as if you had just experienced setbacks. Because it happened recently, it has a great psychological impact on you. It will not be completely calm for a while, but this sadness will dissipate. Why? Because your dream is far more terrible than reality, in contrast, reality is a little more difficult, but far better than nightmare, so this dream is to help you adjust your mentality and give you a psychological advantage in dealing with the current difficulties, because you have experienced more terrible things, and I believe you have already felt this way after seeing ghosts.
