Personally given the story and symptoms we had it's clearly more than obsession or imagination at work, there is "something" which is beyond usual rationality at play here. And it's good, definitely not evil at all. But then is it the split-souls from the beginning meeting again and supposed to help ascend humanity bla bla? As you said Klairic, how anyone can truly know? I think it is a sign from heaven yes, to change something in our life, to be more and unconditionnally loving for someone else. But how we interpret those signs and how we deal with them is ultimately each person's story to be written by him/herself...
