Analysis of the dream by my Father

Dear Son,
Your dream and the length of it are interesting.
The ball of fire is nothing but the fire that burns out the impurities and shows us in true and unadulterated from.
The choice between wife and father is not of much significance as the choice is between the new road of life and the old beaten road that is familiar. One gets into the new road after traversing the old road for a distance.
You have chosen for once to see the old familiar road to reassure yourself that the road still exists and saw that it really is still there.
As to the old school and the class room episode, yes, it is true that you were not speaking much for the fear of stammering but you knew all the answers and so were scoring well.Your father guiding you in such situations is quite normal and you were seeing the invisible because your daddy was and is always in your thought process but not visible to others.
Returning to Daddy is only a feel or reliving of the old times when the son looks to Daddy for support and assurance.When the son enters adolescence he tends to estimate himself more and starts disassociating with the middle aged parents, goes about finding a partner to match his energies and satisfy his inner urge.But after a decade or so when he settles into a married life and begets children he starts the father's role and starts realising the importance of the father in his life.Then he wants to tread the old path and relive the old days just to cross check if he is really doing his role well like his father. The ball of fire is an awakening in you to tell you that the new road you have chosen is nothing but an extension of the old one that has taught you the rough and smooth and to remind you that the new road also will be rough and smooth.
It is just preparing you for the parental life ahead.
All the best.
Daddy.
