I Am Scared To Be Myself

I have this ability to see death. It all started when i was 15. I had this kind of weird dream about the sister of my grandma. She was talking to me about her life and all of a sudden she look at me and i saw sadness in her eyes and she told me "i'm about to die please tell my family to visit me before i die. Make it urgent, i don't know how much time i have. Please.. Please.." and it's end there. I actually disregard it because i thought it was nothing i didn't tell anyone about it. After a month my grandma called me that her sister died and left a letter for me which is so unusual because we are not even close. When i got the letter and read it i was so shocked "why you didn't listen to me? I died alone. I only want to say goodbye to them. What took you so long?" That's it. I was really really trembling that time. And so the nightmare start. I dream a lot of deaths about my neighbor, about my friend, about someone i just saw online, about a celebrity and they all died. They talk to me in my dream. And i ignore them. I have nothing to do with them. I have no idea when they are going to die. I'm actually scared and i don't know if it is a gift or a cursed...
