Am I psychic, its crazy but could it be true?

This sounds absolutely crazy, but I'm starting to believe I can see premonitions. a few months before my grandma died of cancer, i kept having feelings and images of one of my grandparents dying from cancer mainly my granddad. 4 weeks before my friend died, the last day I ever got to see her, the first thing I thought to myself was she will die by the age of 20 (she had a heart problem). Before my cousin got divorced I had a dream she was going to divorce. My grandad is now going to die from cancer, before we found out I kept having thoughts that something close, like a lost brother or aunt would die from a terrible illness. Could this be signs?
