hi, i know how you feel.
i always think the world is going to end while im alive with things like that. my main worry is water. i have never been in a bad situation or anything with water though.
i have a lot of nightmares where i am running away from waves that are about to go over me. i have a lot of nightmares where my house and all the houses in the world are sinking down and the water is rising above it and everyone is dying.
its horrible
maybe you have a 6th sense or something though about your dreams coming true and that.
