I have been watching in amazement and researching online to verify some details, eg the Greada Treaty signed in 1956 between aliens and the then US president. It has convinced me something is going on, whereas before I was a bit sceptical. Also, when they interview high-up military officers who can now speak out because they are retired and who verify the program's claims, it gives one pause for thought!
I have no medical qualifications but I have heard of personality changes following a head trauma. I think you need to see your doctor and maybe investigate this with an MRI or cat scan. Don't take any chances with your brain. (BTW, I've also read that transplant recipients often take on some of the characteristics of their donor, like food preferences or hobby interests. Strange. They put it down to the DNA of the donor organ becoming part of the entity of the recipient.)
Good luck!
