Here is my take on the subject. The tunnel is where we to to meet God and the person you call a lesser God is the angel of death. When anyone dies they are greeted by angels who remove their soul.
One is for the left foot, one for the right foot, one for the hand and one for the other hand. Now depending whether the person was evil or good, the soul comes quickly, sort of like the movie Ghost where you saw the black people coming for the evil man who killed Patrick Swayze.
Now the Angel of death circles the person dying and comforts him not to be afraid and he escorts the dead person through the tunnel up into the heaven to meet God. There God tells the man "Peace" and after that he is escorted back to his grave.
Depending on whether he is good or not he is punished in the grave. A good person will have his grave huge and comfortable and the scent of musk from heaven fills the grave. An evil person will have the grave press on him and the grave will be so small that his ribs will cave in on each other in absolute pain.
Now many times I have seen my dead husband come to me Rudi and it is always through a tunnel. It takes him days and days to get here. The first time I saw him I screamed and cried and God took him away quickly. I learned from this when you have a gift from God to cherish and appreciate the time you have together.
Well this is my take on the tunnel aspect anyway.
