Nightmares about losing your pets, etc

I'm just wondering if others have nightmares that their pet has runaway or he/she dies. Or that you are trying to rescue them from a burning building. I'm wondering if this is a common nightmare of pet owners or if it is my own problem, lol.

i have nightmares of picking fleas off of her cuz that's kuan yin's issue at the moment (as she is too young and small for frontline and all i can do is comb her and give her baths). but i get paranoid when i'm awake..thinking about all the things that could happen to her or in what horrific position i could find her in the house over something i missed or forgot. i think it's a sign of just being a really good meowmy :-)
