Pretty much 99% of the time I take a nap I wake up in a panic attack to the point where I don’t like naps anymore. 

I’ll give a little context. A little over a year ago I was in a bad rollover accident. And my dog died. Everyone was fine minimal injuries. I don’t think I have ptsd. I feel bad and have thought about my dog every day since then. I always think about the dozens of things I could have done different that day. The many coincidences that occurred in the days up to the accident. Like the universe warned me. We hit ice. I was in the backseat with her by my side as she slept. When we started sliding I put my hand on her. But I kept looking out the windshield as we kept rolling off the road. I froze and I totally feel like I could’ve saved her. 

Anyways every time I take a nap during the day I wake up in a small panic attack suddenly realizing my dog no longer here. This doesn’t happen when I sleep at night only during the day.
