what feeling doe's the human feels when dieing .?!

I don't think anyone really could tell you that because they would be dead

depression is common. but it will depend on a person on how he accepts death then.

initially, a person will undergo the coping process called "DABDA" (The five stages of the Kübler-Ross stage model). It is the best-known description of the emotional and psychological responses that many people experience when faced with a life-threatening illness or life-changing situation. But it can also apply to those people who are in grief. Reactions to illness, death, and loss are as unique as the person experiencing them.

Denial -- Coping usually begins with the person thinking "No way, not me."
Anger -- "Not me" will usually give way to "Why me?" as the person begins to accept the reality of the illness and becomes angry.
Bargaining -- As anger subsides, or even in it's midst, the person may begin to bargain for more time.
Depression -- When it becomes obvious that bargaining won't work, depression may set it.
Acceptance -- If the person is able to move through one or more of the previous stages, they may be lucky enough to reach the stage of acceptance before death.

Very peaceful, like God gave you a tranquillizer...I haven't died, yet in this life lol, but many times I was dying, and I was always at peace and not at all afraid.

Go to a hospital and ask some terminal patients.

How would someone know.......?

F*ck, is that all????
