This disorder is called hoarding disorder. Hoarding disorder is characterized by difficulty in disposing or separating from one's belongings, even if those items have become garbage.

This is because of the need of the sufferers to save or secure those items. Even hoarding disorder sufferers are willing to disregard the comfort inside the house in order to maintain their belongings.

Like what an elderly woman experienced in Woodlands, Singapore, here. She was willing to sleep in the apartment corridor with a cardboard base because her house was full of used items.

According to Mothership website, the woman who lives in apartment block 603 Woodlands Drive is said to have been behaving like that for over 10 years.

According to her neighbor, the woman lives alone in the apartment and is often visited by her brother. Despite being repeatedly forbidden to sleep in the corridor, she continues her activities.

A neighbor said that volunteers usually visit the woman and bring food. Some neighbors also feel sorry for her and occasionally bring food for her.

A neighbor even occasionally cuts the old woman's hair, helping her maintain the cleanliness of her clothes, and so on.
