After watching the Korean horror movie "The Doll Master", I reflected upon what one of the characters said in one of the scenes: "In life, it is natural that humans get attached to non-living things, such as the dolls played by children. Usually, when we get too attached to a certain thing (eg. a house, an item, etc...) it begins to form a soul in itself, like as if it becomes alive, similar to a living being staying with us."
A spirit enters and exits a doll through the doll-eyes. If you ever find out your doll to be haunted or possessed by unknown spirit, you must do the following 3 things in sequence:
1. use a sharp object to dig out the eyes.
2. twist and break the doll's neck and pull the head out.
3. quickly set the whole doll on fire to burn it all away.
It is not surprising or rare to discover, as well, that some adults these days have a hobby of keeping all kinds of elegant expensive dolls in display at home. However, as a word of precaution, do not buy or adopt dolls which look weird or feel strange to you. Do not use dolls for black magic or voodoo or evil purposes, as you risk meddling with powerful spirits you do not know. Do not curse a doll, what goes around comes around. Do not purchase dolls from unknown or uncertain sources. Dolls can be kept as a hobby or for beautiful display in the house, but do not get obsessed with it.
