What are these headaches?

OK, so I got those headaches like 5 years now, and they're like dull pain mostly in the back of the head... Now it hurts for like 3-4 seconds and then slowly reduces the pain. The last time I had a headache brought an inner voice, and it said ''Prepare for touching the land'' that day, in school, i like fel of from the stairs (about 2.5 m high) and totally owned myself... I was OK, no injuries. Then on the Big Friday I was guarding Christ's grave (tradition) and I fainted, but also had a vision. I have seen my 2 girl friends (friends, not GF's) like they we're talking on the 30th of April (I know the date because I felt like I need to go to the concert, and the concert was 30th may) at 10 AM (the time I left home, that they we're talking about ''my life call'' (medicine), and about how the want something or someone and then Helen said that she wants it too... And that really happended... I know that it's strange asking it so late, but I only got her to answer today. So I would like you to ask you, those who have experience or know why this happens, to tell me the reason and explain it for a bit. First ones get Best answer.
