Hi,
could it also be something beside yourself causing this ? I am thinking of that many people, over 1,500 people ( so many souls ), having a trauma, dying this way around the same time ? Having this in common ? Could one then be experience a form of a connected-spirit- group-death-anxiety ?
Then perhaps as a further away reaction all the people who were in one way or another effected by the Titanic tragedy ( my daughter was very young when Titanic was shown on the television and she demanded to see it, no matter how we tried to talk her out of it, she did not understand the language even, but she still insisted and she saw it all as if this was her duty or something. I would take my hands over her eyes when ever there was something terrible going on though but she hated that, was very strong minded "I want to see !" as if it again was her duty, not something she enjoyed, though. I think I know who she could have been in her past life and if so she was then a he, American, and he was then of the age of 22 when it happened. I don't know, but I can imagine that many people would think of, do a type of ceremony each year on your past life death date to show respect of the departed souls of the Titanic ).
