Well it's been a while since my last one, once I realized that I was in my head it became so easy to just get rid of them. But one I can remember was shortly after my Family had to evacuate from Beaumont to Denton because of Hurricane Rita.
From what I remember about it, we were in a convenience store that we stopped at during the evac (That was hell to go through by the way, My cat at the time almost got Heat stroke from it due to lack of AC in the car.) We heard someone scream outside and ran out to see what was going on, and we saw the Rita... from about 200 miles away, coming fast. (I was young so I didn't know what it actually looked like, so it just looked like the underside of the orbital pictures) The reason it stuck with me is because of how my family reacted, way to accurate for my liking, and that terrified me.
