First of all, sleep with your head facing south. Sleeping with your head facing south may make people feel very excited and easily lead to insomnia and dreams. From the perspective of geomantic omen, it is suggested that you decorate your bedroom with yellow sheets, because yellow can soothe the nerves and relieve insomnia. Try not to decorate the bedroom with light-colored furniture, because light-colored furniture will stimulate people's brains and may cause insomnia.
Secondly, let's talk about sleeping with our heads facing northeast. If you sleep with your head facing northeast, you may feel very nervous, so you may be more active when you sleep, and your dreams are generally not very good. Some people may be awakened by their dreams, but some houses have to sleep in this direction. If it is a last resort, we suggest that you decorate your bedroom with dark furniture.
Finally, sleep with your head facing east. The sun rises in the east, so according to the magnetic field, sleeping with your head facing east can make people get up early. After all, a day's plan lies in the morning, and only by going to bed early and getting up early can you have a good spirit, so we think that sleeping with your head facing east is the best choice. However, the specific sleeping direction still depends on your own habits and preferences. These are also some suggestions for your reference.
