Bears. Ever since i was little i have always had dreams of bears comming and attacking my family and killing everyone. Ive never seen one in RL (besides the zoo) but if i ever did i dont know what id do!
Tornado's. Same ordeal, always had dreams for as long as i can remember, and last year i actually witnesed my first one. I was home alone and it tore right through my backyard. Scary scary scary.
