Sit back and let us look at the recollections and impressions of the
    dead themselves,well actually to people that were clinically dead.
    A person is proclaimed clinically dead when his heart stops
    beating,therefore the body can not function.Today there are many reports
    about people that after they "died" have miraculously returned to the
    living.Some of these people bring with them stories that are supposed to
    be about the world beyond.
    One of the more colorful reports was told by a man who had been
    involved in a car accident,he has been rushed to the hospital where
    he will be proclaimed dead but then return to life and tell this story:
    "Later I saw a flash of light and I found myself floating above my
    body,I could see how the surgeons were working on my body.A nurse was
    seated above my head.The next feeling I felt was that someone put a hand
    on my shoulder and then I had the sense of sitting on something and
    moving through a tunnel.". The speaker continued saying that after he
    passed the tunnel he found himself in a foggy place where he could see
    only the figures of entities that were moving and that everything was
    flooded with a pleasant kind of music.One of the entities came close to
    him and asked him about his life and instructed him to return to his
    body,at this point he woke up.

    Not all recollections are so pleasant,an example for less pleasant one
    was given by a woman who had a heart attack,the recollection was taken
    down by the doctor that reanimated her: "I felt out of breath and I
    fainted.A few seconds later I found myself out of my body and entering a
    dark gloomy room with windows.In one of the windows I saw the twisted
    face of a giant in the others I saw little demons.The giant gave me a
    sign to follow him,I did so reluctantly but I had no choice.On the
    corridor things got worse,I could hear other people groan and I felt
    something moving under my feet.Then all of a sudden the giant let me go
    and I woke up in hospital.". The woman didn't take any drugs and she had
    no reason to fake the report.

    These two recollections have been of the next world but most of the
    recollections are a lot simpler and can by some people be even called
    Astral Projections.In most cases people have reported to have been
    pulled out of their bodies and hovered above them where they could see
    that they are dead and the doctors are trying to save their lives.
    The astounding fact about this phenomena is that people that reported to
    see what was going on could give a very accurate report and they could
    describe many complicated medical procedures that they could have not
    known unless they studied medicine,a thing they didn't do.


    The problem with the dead that came to life is that their claims in many
    cases are so weak that skeptics have no real problem to prove them as
    either fakes or people that don't know what they are talking about.The
    first two recollections simply can't be proved but the possibility that
    those two recollections were of heaven and hell is possible and people
    with similar recollections have been found. The skeptics say about the
    two kinds of occurrences that the brain may react to intolerable pain by
    creating hallucinations which creates the persons individual hell or
    heaven.The brain,since the person knows that he is on verge of
    dying,creates hallucination that has a connotation to that
    notion.Another fact that the skeptics use is that when the heart stops
    beating the brain doesn't get any oxygen and that is sure to cause
    hallucinations.But still skeptics can not explain cases in which
    patients have been connected to machines that scan brain activities and
    have shown none. A harder nut to crack though are the people that have
    claimed to have left their bodies and are able to describe complex
    medical procedures accurately.The skeptics claim that these people may
    have an input device to their brain still functioning while they are in
    coma and in that case they could obtain the information but that hadn't
    been proved either. Another possibility is that these people projected
    their Astral Body and hadn't actually died although the machines said
    so,but this too is a supernatural explanation. This part of afterlife
    research has been disregarded but today there are more and more people
    that claim that they have died and returned,to my opinion such cases are
    nothing more then Astral Projections or hallucinations caused by people
    in agony but,you can never know...
