The bedroom window is half blocked by the outer wall. How to resolve feng shui?

Feng Shui master pointed out that sleeping in a room with a big window facing east or west is easy to lead to a "bloody disaster" because of "lightness". Because in a room facing east or west, the fierce sunshine in the morning or afternoon will lead to too much light in the bedroom, stimulate nerves, affect rest, thus leading to insomnia, and even make people restless and impulsive. Feng shui master suggested: choose a small window room facing north or south as the bedroom. If you have lived in a room facing east or west and it is impossible to change it for the time being, then pay attention to closing the curtains at the right time.
