It may be a bed, because the comfort, size, hardness and other factors of the bed may affect the quality of sleep, leading to MUBI or less dreams. However, there are other factors that may cause you to sleep at home, such as family environment, family atmosphere, living habits, schedule and so on. If you sleep in noisy environment or tense family atmosphere at home, it may affect your sleep quality and lead to MUBI. If you often stay up late at home or work and rest irregularly, it may also affect the quality of sleep and lead to MUBI.
If you want to determine whether it is a bed problem, you can try to change a bed or adjust the position of the bed to see if it can improve the quality of sleep. If it is still MUBI after changing the bed or adjusting the position of the bed, it may be related to other factors, so it is necessary to further find out the reasons and adjust the living habits and environment.
