I have this feeling all the time! When I was little, I was extremely worried about my parents dying. I'd stay up crying all night, thinking that something was going to happen to them while I was asleep. Now a days, I have this eary feeling that I'm going to die any second, or the worlds just going to end. It gets really strong some days and it gives me the willies.
But, I'm still here, the world is still here, so I doubt this is my intuition talking
