DEATHBED VISION; WHY DYING PEOPLE SEEM TO SEE VISION ON THEIR DEATHBED?

Death bed visions are the visions or experiences that a dying person may have in the moments before his or her death. Family members and hospital personnel have often reported  that a dying person previously weak, disabled or invalid  were suddenly revived  and showed the signs of them seeing things.

For example,dying people have described seeing or hearing things other people who are not physically present  and are usually deceased . I remember when my grandmother was dying ,she kept on saying that she can see my grandfather who died ages ago calling her "hmmmmmmm". Deathbed visions are also accompanied by odd events in the environment  like things falling off the chair ,a strange wind blowing. Some reportedly even see angels and some see familiar people who had previously passed away telling them that they have come to take them away. When this happens ,the dying person tends to be elated and it seems like he or she has recovered....we hear of stories of people saying "he\she actually recovered and was full of life ,how come he\she is dead?.

Do you have any story of deathbed vision? please share your experience?
