That may or may not be a fair point, Jack ~~ but I don't think, if I may be so presumptuous, that 'imagination' is a particularly judicious word to be employed from your side of this question, bearing in mind that our point over here is that your entire concept of the facts is 'imaginary' ~~ whence 'imaginary friend' &c. I should look for a synonym IIWU: 'inspiration', perhaps.
