Hello mates, how have you been?
T's been a long time since my last access here, cancer got me by surprise and really hard, so, chemo all the way and no time to care with much more.
Anyway, going to the point.
Have any of you ever heard folk songs? Medieval folk songs, I mean, like Tam Lin or Unquiet Grave? Well, since I'm Brazilian, I hadn't until some time ago, and... Well, I don't know if it paranoia or something else, but it seemed that most of those songs described some rites and sometimes outright spells! And although the people involved changed in other versions of these songs, the rite was still there, always. Like Unquiet Grave, 12 months and 1 day of mourning over a grave and the fetch of light from a deep cave and the other things.
Anyway, my question is: Is there any sense in this or I'm just hallucinating?
