This is not intended to be a morbid post but because of the nature of the topic I guess it is anyway!
Have you ever heard of a long time terminally ill person who could live a few years more yet seem to know that they were going to die in the next couple of days?
My grandfather called my cousin into his room a few years ago and told her that his funeral was happening before his eyes, he could see it, he died that night.
Anyway, back to the original ?, have you heard of similar things? Do you think terminally ill people get an insight into their death just before it happens?
