Robert Frost's "second hearing and second sight"
Frost has always been one of my favorite poets but I never knew much about his life. I did a search and came up with a ketzle.com/frost/frostbio.htm bibliography of some of the major events in his life. One entry seemed a bit strange to me. In 1883 it says, "Frost hears voices when left alone and is told by mother that he shares her gift for 'second hearing' and 'second sight.'"
Does anyone have any information on this? A Google search turned up a few similar articles, but no details. Was Frost a schizophrenic?
