Beckett's Theory of Hauntedness

One theory is that this is someone he's haunted by could be his mother who was widowed for a long time with whom he went to his father's grave several times. In craps last tape he talks crap is talks about his mother dying and i see flashes of that in the show. The character doesn't know what viduity means so he has to look it up in giant dictionary but they were times when i saw that  and i consider that yeah it's it's mom it's mom i mean i feel like there are some similarities between these two scenarios.
