According to the sadly-former-atheist John C. Wright, when he gets these hugely powerful "religious experiences", he gets the Trinity - yes, the good 'ol fashioned Trinity - talking to him directly.

This would seem to be some weird levels-of-abstraction confusion: the Father and the Son can influence you through the Holy Ghost (qui ex Patre Filioque procedit), but claiming the Trinity as a whole is talking to you seems to me to be double-counting evidence.
